As Newton once said, "Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things." It’s like in language: why say "a round object used in games" when you can just say "ball"? The author found a simple, logical relationship that ties together the relevant measurements to address the issue. That above is nothing more than a representation You do not do any calculations from it. That takes further details. There is nearly 30 different tensors hidden under that expression. You need to factor out the relevant terms in order to apply them. lets demonstrate all of this is contained under that above expression and that is ONLY A TINY PORTION.

Majorona fermion has its own antiparticle pair while Dirac and Weyl do not. The RH neutrino would be more massive than the LH neutrino, same for the corresponding LH antineutrino and RH Neutrino via seesaw mechanism which is used with the seesaw mechanism under MSM. Under MSSM with different Higgs/higglets can be numerous seesaws. The Majorona method has conservation violations also these fermions must be electric charge neutral. (must be antiparticles of themselves) the CKM and PMNS are different mixing angels in distinction from on another. However they operate much the same way. CKM is more commonly used as its better tested to higher precision levels atm. Quark family is Dirac fermions due to electric charge cannot be its own antiparticle.

In relation to cosmological constant. everything in that math is what the Author ignored when he states SU(3) all those equations are for quark mass terms. the Higgs mixing angles are included for symmetry breaking this is what the author expects you guys to piece together. So its VERY relevant to the discussion Nothing there will give mass to photons... Edited October 30 by Mordred

In the beginning of the thread I asked about the path to experimental confirmation. If you’re going to appeal to this, let’s see the evidence of these SU(3) atoms or the superconducting nature of dark energy.
MigL Posted October 30 Posted October 30 4 hours ago, JosephDavid said: we know that protons don’t decay and are associated with SU(3) symmetry, then it makes perfect sense to use the volume of the proton as the benchmark for this remnant state You don't see that this is an assertion with no evidence, physical or mathematical, to back it up ? It just so happens to slot into your pet theory, so you run with it. Why not pick the hydrogen atom as the remnant volume ? Or why not up/down quarks as remnant volume since they are also stable, and involved with SU(3) symmetry ? I suspect it's because it doesn't produce a neat answer with numbers that match the magnitudes you require for your pet theory. Until the foundation is solid, and if you ( the author ) can connect all the dots, it is just a theory based on numerology. 1

Well, hydrogen is a little more complicated. It’s made of a proton and an electron and that electron’s got U(1) symmetry written all over it, which breaks at low temperatures. So, hydrogen isn't the best candidate because it's tied to electromagnetic interactions, not exactly stable if you're looking at what happens when U(1) breaks. The proton, though? That’s a different story. Now, about quarks. Sure, up and down quarks are part of the SU(3) game, but they’ve got a problem: you never find them alone. They’re always confined, stuck inside protons, neutrons, whatever. Quarks are like that friend who never leaves the party alone, they’re always bound together, thanks to quark confinement. The proton, on the other hand, is the smallest, most stable package of SU(3) stuff we can actually observe. It’s been tested again and again, and it’s never been seen to decay. So why pick the proton as the remnant volume? Because it’s the simplest stable bound state that’s pure SU(3). It’s the one structure that stays unbriken under the third law of thermodynamics, when you get to those really low temperatures, it’s still standing. That’s what makes it perfect for this context. We need something stable, something minimal, and something that stays intact with SU(3) symmetry. That’s the proton. It’s not just a random pick, it’s the only choice that makes sense if you want a fundamental remnant that’s consistent with what we observe in the vacuum. 1

It’s not just a random pick, it’s the only choice that makes sense if you want a fundamental remnant that’s consistent with what we observe in the vacuum. let me ask a different question which people have looked at what zero point energy entails ? Ie which field does it apply to ? All quantum fields have a ZPE ground state this includes all quantum field at the closest QM/QFT allows to absolute zero. Doesnt matter if they are massless or massive or complex mixtures. Every quantum field has a ground state. So what difference would it make to leave the Complex SU(3) field untouched via symmetry breaking if every other field still contributes to the total energy or rather all quantum particle fields draws from the infinite quantum ground state under QFT treatment( where the position and momentum operators are treated at every coordinate for the oscillator field) specifically any quantum field that has not been normalized via the reduced Hamilton ? You could have every single quantum field at absolute zero or any other temperature and still have a ground state The uncertainty principle states that no object can ever have precise values of position and velocity simultaneously. The total energy of a quantum mechanical object (potential and kinetic) is described by its Hamiltonian which also describes the system as a harmonic oscillator, or wave function, that fluctuates between various energy states (see wave-particle duality). All quantum mechanical systems undergo fluctuations even in their ground state, a consequence of their wave-like nature. The uncertainty principle requires every quantum mechanical system to have a fluctuating zero-point energy greater than the minimum of its classical potential well. This results in motion even at absolute zero. For example, liquid helium does not freeze under atmospheric pressure regardless of temperature due to its zero-point energy. https://en.wikipedia.org/wiki/Zero-point_energy so Just how precisely is SU(3) going to solve the vacuum catastrophe if every other quantum field still contributes ? Symmetry breaking or not..... look at graph showing the ground constant at all temperatures... perhaps that will help you understand precisely why I kept mentioning Bose-Einstein and Fermi-Dirac statistics for particle number density ALL fields contribute and ALL fields draw from it for particle creation/annihilation at all temperatures. All quantum fields have harmonic oscillations regardless of temperature. Yet the author claims to somehow magically solve this by leaving SU(3) unbroken in symmetry On 10/23/2024 at 9:17 PM, Mordred said: Here is a simpler breakdown using operators ie QM or QFT which would have been far easier to apply symmetry breaking with regards to the paper https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://faculty.pku.edu.cn/_resources/group1/M00/00/0D/cxv0BF5mDfKAOPDbACEBbOQBol4139.pdf&ved=2ahUKEwj-jdiwhaaJAxWvJTQIHZQ3C58QFnoECDYQAQ&usg=AOvVaw0bF6zGAJhSK_UcqzuzVZ4o There is a reason why the vacuum catastrophe is also called the EM field ultraviolet catastrophe the problem is directly related to how it was renormalized...

So once again I ask what the bugger is an SU(3) atom as the only Langragian the author included was the QED langrangian. Thats why I mentioned these equations back on page 5 please read the article in that link.. it will reinforce everything I just described. After you do that , think back on the video MigL posted. then relook at the following from page 1 "lets detail the cosmological constant problem then you can show me how your paper solves this problem I will keep it simple for other readers by not using the Langrene for the time being and simply give a more algebraic treatment. ( mainly to help our other members). To start under QFT the normal modes of a field is a set of harmonic oscillators I will simply apply this as a bosons for simple representation as energy never exists on its own \[E_b=\sum_i(\frac{1}{2}+n_i)\hbar\omega_i\] where n_i is the individual modes n_i=(1,2,3,4.......) we can identify this with vacuum energy as \[E_\Lambda=\frac{1}{2}\hbar\omega_i\] the energy of a particle k with momentum is \[k=\sqrt{k^2c^2+m^2c^4}\] from this we can calculate the sum by integrating over the momentum states to obtain the vacuum energy density. \[\rho_\Lambda c^2=\int^\infty_0=\frac{4\pi k^2 dk}{(3\pi\hbar)^3}(\frac{1}{2}\sqrt{k^2c^2+m^2c^4})\] where \(4\pi k^2 dk\) is the momentum phase space volume factor. the effective cutoff can be given at the Planck momentum \[k_{PL}=\sqrt{\frac{\hbar c^3}{G_N}}\simeq 10^{19}GeV/c\] gives \[\rho \simeq \frac{K_{PL}}{16 \pi^2\hbar^3 c}\simeq\frac{10^74 Gev^4}{c^2(\hbar c)^3} \simeq 2*10^{91} g/cm^3\] compared to the measured Lambda term via the critical density formula \[2+10^{-29} g/cm^3\] method above given under Relativity, Gravitation and Cosmology by Ta-Pei Cheng page 281 appendix A.14 (Oxford Master series in Particle physics, Astrophysics and Cosmology) Edited October 30 by Mordred
Mordred Posted October 30 Posted October 30 (edited) notice the integral from summing over momentum states ranges to infinite but the term includes a constraint to prevent that RHS of the \(\int^\infty_0\) that was the regularization term that led to vacuum catastrophe Posted on page 1 That is what needs solving so how does SU(3) solve that ? LMAO I lost count the number of times I stated ENERGY DENSITY this thread.... so earlier I also showed the math showing there are 16 fields which means 16 fields each with a ZPE for QCD as SU(3) for simplicity. Just an FYI to everyone reading for the harmonic oscillator the Operators are Hermitian so it will be equal to its adjoint as all Hermitian operators are. Just in case anyone familiar with Hamilton forms are reading. May also help with sections in regards to the wiki link above (operators being the Hermitian position and momentum operators). What this means is the harmonic operator raising lowering (ladder operators) aka creation/ annihilation operators are also Hermitian Edited October 30 by Mordred

swansont Posted October 30 Posted October 30 9 hours ago, JosephDavid said: So why pick the proton as the remnant volume? Because it’s the simplest stable bound state that’s pure SU(3). It’s the one structure that stays unbriken under the third law of thermodynamics, when you get to those really low temperatures, it’s still standing. That’s what makes it perfect for this context. We need something stable, something minimal, and something that stays intact with SU(3) symmetry. That’s the proton. It’s not just a random pick, it’s the only choice that makes sense if you want a fundamental remnant that’s consistent with what we observe in the vacuum. What you’ve described is convenience, not something based on either experiment or theory. There’s nothing wrong with picking a convenient reference up until you assert there’s something physically meaningful about it.

It also is just first order terms. The reason being for that is the specific action of a harmonic oscillator. Linear only with no non linear components in the above. Now if the above shows the catastrophe is linear read the wiki link under QCD as a complex system will comprise of non linear components. (The tensor fields under SU(3) as one example ) which includes longitudinal and transverse components where the above is longitudinal. If you study the oscillator equations that gives rise to the 1/2 term just prior to the energy momentum under the square root. (Hint U(1) symmetry only in above) do not confuse that as EM only. EM field also has non linear terms Edited October 30 by Mordred

MJ kihara Posted October 30 Posted October 30 ....In Quantum Field Theory (QFT), as discussed by Steven Weinberg [19], the vacuum energy density arises from summing the zero-point energies of quantum fields, including massless bosons like photons and gravitons. It is calculated as: ρ QFT vac c2 = (2π1ℏ)3 Z 0PPl d3p ℏω p 2 , (17) where PPl = EPl/c is the Planck momentum, and ωp = c|⃗p| for massless particles. Integrating up to the Planck scale yields: ρ QFT vac c2 ≈ E 4 Pl ( ℏc )3 ≈ 1076 GeV4/(ℏc)3 Page 18 of the author article....they are considering all fields,and his cut off is planck scale, meaning that it's taking care of volume smaller than the on considered by SU(3) symmetry unit. Your approach and this one which one is more advantageous?

Well, the choice of the proton isn’t about convenience, it’s about its physical significance. The proton is stable; we’ve never seen it decay, and it stands strong under SU(3) symmetry, even when U(1) breaks down. That’s what gives it physical meaning beyond just being a handy reference. It’s not a random choice, it’s a backed by what we know from experiment and theory.

Your approach and this one which one is more advantageous? Ok were going to have to teach you latex above is difficult to read. Anyways take a particle under QFT all particles are field excitations. In terms of ZPE the more you determine localize the position via Compton/De-Debroglie wavelengths the more uncertain you are on its momentum. 26 minutes ago, TheVat said: Following only tiny (Planck scale) bits and pieces of the chat here.

We cannot measure anything less than a quanta of action See here for other readers how that connects to Planck constant and ZPE. https://en.m.wikipedia.org/wiki/Action_(physics)#:~:text=Planck's quantum of action,-The Planck constant&text=%2C is called the quantum of,and the de Broglie wavelength. Now the planck length is the smallest theoretical measurable wavelength. How many planck lengths in the Observsble universe ? Give anyone and idea of the momentum space trend to infinite energy?

JosephDavid Posted October 31 Posted October 31 8 hours ago, MigL said: Sorry my mistake; meant to write Helium atom. Stable, and a superfluid. Good question indeed. As you get closer to absolute zero, the third law of thermodynamics is saying, "I want a system that’s as orderly and low-entropy as possible." Now, look at liquid helium. Sure, it’s fascinating stuff—flows without friction, does all sorts of quantum tricks. But even down there near zero, it’s still got a lot of atomic hustle and too many possible states, which means higher entropy. Enter the proton. This thing is rock-solid, It’s stable, and has very few microstates to mess with, exactly what the third law ordered for a low-entropy, high-order setup at the coldest extremes. So, if we are looking for the perfect fit for a minimal-entropy remnant, the proton’s our guy. 8 hours ago, MigL said: Observation of a Casimir effect between separations of less than the 'proton volume' ?

Can you give more details? 7 hours ago, swansont said: You have not connected it with anything. It’s not like it’s the volume of the proton that keeps it from decaying. Free neutrons decay. It’s not just about volume, what really matters is remnant volume with minimal entropy. The third law of thermodynamics is looking for something stable and with the least possible disorder. Now, the neutron might look similar in size to the proton, but here’s the catch: free neutrons don’t stick around, they decay, and that means extra entropy. The proton, on the other hand, is rock solid. It’s stable, no decay, and has minimal entropy because it doesn’t have extra states to fall into. So if you’re looking for a low-entropy remnant that satisfies the third law, it’s the proton that wins.
Mordred Posted October 31 Posted October 31 (edited) @JosephDavid I understand your not familiar with the mathematics so anytime I supply mathematics it doesn't relate to you as your unfamiliar with the equations. Don't worry its very common on any forum. So your in good company. My challenge has always been how do I get explanations across that don't rely on a mere matter of trust of my opinion. One might think well I could merely post articles and quote sections etc however that actually doesn't work very well. for example pertinent to what I'm going to describe below if I were to say look at equation 44 to 48 of this article on QCD superconductors comparing the QED superconductors later is I couldn't expect a large majority of our members to understand it. https://arxiv.org/pdf/0709.4635 I could for example in terms of this thread explicitly show that the Meissner effect cannot fully describe a QCD vacuum state via the mathematics. The Meissner effect specifically involves the electroweak symmetry vacuums. So here is my challenge in a nutshell a very clear distinction is the electroweak couplings as opposed to the QCD couplings for color gauge using Yang Mills and the Gell-Mann matrices. This is the electroweak couplings to Higgs field for the electroweak bosons. \[W^3_\mu=Z_\mu cos\theta_W+A_\mu sin\theta_W\] \[B_\mu= Z_\mu sin\theta_W+A_\mu cos\theta_W\] \[Z_\mu=W^3_\mu cos\theta_W+B_\mu sin\theta_W\] \[A_\mu=-W^3_\mu\sin\theta_W+B_\mu cos\theta_W\] What this shows is that the charge conjugate mediation has different coupling strengths. It also shows that the above fields are Abelian also the longitudinal components of the above is your mass terms via the energy momentum relation. Which is essentially what is also applied for the zero point energy equations longitudinal plane waves. This however is not the case in color charge mediation Which for the Miessner effect is described by BCS theory in the above (the EM/EW fields) in the above you get Cooper pairs with flux tubes providing current flow between the Cooper pairs this is true in both type 1 and type 2 superconductivity. However those flux tubes involve the E and B fields for the EM field> how that works for weak field superconductivity involves charge conjugation. Earlier I posted the charge conjugation formula. \[Q+I^3+\frac{\gamma}{2}\]. Now here is the problem with the above with color gauge. interactions (sorry this does require math) its unavoidable. a quark is described by two wavefunctions a Dirac wavefunction and a color wavefunction for the SU(3) mediation Dirac wavefunction \(\psi\) color wavefunction \(\Psi\) \[(i\gamma^\mu \partial_\mu-m)\Psi=0\] color wavefunction below \[\Psi=\psi(x)\chi_c\] the colors are below \[\chi_R=\begin{pmatrix}1\\0\\0\end{pmatrix}\] \[\chi_G=\begin{pmatrix}0\\1\\0\end{pmatrix}\] \[\chi_B=\begin{pmatrix}1\\0\\0\end{pmatrix}\] to be a gauge theory one requires invariance under Dirac invariance. (includes Lorentz invariance) \[\acute{\Psi}=e^{i g_s}{2}\alpha_j B_j(x)\Psi\] I won't bother with the mathematical proof of the last expression however the inclusion of the color gauge fields to the Dirac wavefunctions gives the Langrangian of \[\mathcal{L}=\bar{\Psi}(i\gamma_\mu D^\mu-m)\Psi-\frac{1}{4}F_{j,\mu\nu}F_j^{\mu\nu}\] with a field strength tensor of \[F^{^{\mu\nu}_j=\partial G^\mu_j-\partial^\nu_j=g_sf_[j,k,l}G_k^\mu G_l^\nu\] now what that above expression tells us is that the coupling strength for each gluon mediator 8 in total is identical. Now I'm going to skip a bit in order to mediate the color gauges between quarks you require three Operators \(I_\pm\), \(U_{\pm}\),\( V_{\pm}\) these are the ladder operators for quark color charge interchange. \[(i\gamma_\mu \partial^\mu-m)\Psi=\frac{g_s}{2}\gamma_\mu G^\mu_j(x)\psi\lambda_j\chi_c\] this describes a state \(\chi_c\) with color Couples with the field strength \(g_s\) and changes to another color charge C mediated by \(\lambda_j G_j^G\mu\) I won't go into the fuller color operator expression for each color exchange however the amplitudes for color are not 1/2e as per EM charge color charges are 2/3e or 1/3e so the formulas used for ZPE for those amplitudes are different in wavefunction equivalence due to distinctive difference of the 1/2 EM charges involved for the relevant Meissner effect charges for Em=\(1/2_\pm\) charges for color \(2/3_\pm, 1/3_\pm\) The above qualitatively shows that the field mediation for color charge is significantly distinctive from those of the EM field. This demonstrates that the Meissner effect as per BCS theory or the Anderson-Higgs field do not describe a superconducting QCD vacuum state. for 3 reasons. 1) abelion fields vs non abelion fields. 2) color vs EM charge 3) different coupling strength relations across the mediator fields (EM =different coupling strengths for each mediator as opposed to one coupling strengths for all mediator bosons under QCD 4) the interaction field (mediation requires 2 wavefunctions thereby making it a complex field=added degrees of freedom= higher field number) 5)as this would require significantly more the math I won't delve into it the VeV calculations would be different from a QED VeV from a QCD VeV. Everyone might also note the the above article is looking at 6 Cooper pairs for for QCD vacuum its one of the possibilities. another being Dual Miessner Edited October 31 by Mordred

But how is this related to the SU(3) minimum volume stability ? You cannot use the same thermodynamic considerations to argue for 'volume' stability. And 'volume' is what you are using to subdivide the unreasonably high vacuum energy, not protons.

And 'volume' is what you are using to subdivide the unreasonably high vacuum energy, not protons. Your questions made me understand the author arguments more clearly. The proton and neutron might seem similar since they’re both built from quarks held together by the strong force, but they’re not the same when it comes to stability and entropy. Neutrons? They decay, breaking down into a proton, an electron, and a neutrino. That breakdown matters, it means more ways for things to fall apart, more “messiness” or entropy in the system. The proton, though, is different. It doesn’t decay (at least, we’ve never seen it happen), and it doesn’t have any available decay channels in the standard model that wouldn’t violate fundamental conservation laws, like charge conservation. Simply put, it’s stable because the rules of physics don’t give it a way out. So, the proton’s stability is directly tied to these conservation laws. This stability means the proton has minimal entropy, it doesn’t have all those extra states it could move into. And here’s where the third law of thermodynamics kicks in: as a system gets down to close to absolute zero, it demands a setup with as little entropy as possible. This is why the proton fits the bill perfectly. When we’re looking to break down the vacuum energy into stable, low-entropy “units” in the context of SU(3), it’s not just about taking any volume, we need something as stable as they come, with minimal entropy. The proton’s locked-down, conservation-law-protected structure makes it the ideal candidate for this job. So, when we talk about the proton as representing an SU(3) vacuum atom, it’s not just about its size; it’s about its role as the ultimate low-entropy, stable unit in the structure of the vacuum.
joigus Posted October 31 Posted October 31 (edited) So these atoms are there. They're not a vacuum. They're a background. Why is it high-precission tests of the standard model haven't found them yet? Hadrons of all kinds, from high-energy beams and jets would certainly scatter off SU(3) bound states, with a very sizable cross section. On top of that, they are 1043 times more abundant than ordinary neutrons, so the luminosities would be over the roof. Why haven't we seen the littlest inkling that they're there? Don't think for a moment I haven't noticed you aren't answering any of this. This thread is starting to smell with a really foul stink. Edited October 31 by joigus minor correction 1

Protons can decay, after all (beta plus). Just not free protons.
