derek w Posted February 15, 2013 Posted February 15, 2013 Providing you have up/down and anti-up/down quarks,all other particles will be created as side effect.
derek w Posted February 15, 2013 Author Posted February 15, 2013 What about the electron? High energy radiation,creates electron/positron pairs via photon+photon collisions.
ajb Posted February 15, 2013 Posted February 15, 2013 So, you are not suggesting that all "stuff" is made just of quarks and anti-quarks?
derek w Posted February 15, 2013 Author Posted February 15, 2013 So, you are not suggesting that all "stuff" is made just of quarks and anti-quarks? No.Free quarks in a quark gluon soup,would have greater energy than quarks confined in protons,they would have to release high energy radiation to become confined.That high energy radiation then creating electron/positron pairs.
mathematic Posted February 15, 2013 Posted February 15, 2013 Once quarks combine you end up with neutrons and protons. The neutron decay leads to protons and electrons. Question - in this model how did the universe become electrically neutral?
swansont Posted February 15, 2013 Posted February 15, 2013 Providing you have up/down and anti-up/down quarks,all other particles will be created as side effect. What about matter/antimatter asymmetry? Why u/d, if you're creating everything else out of the energy of the system?
derek w Posted February 16, 2013 Author Posted February 16, 2013 If 2 up and 1 down quark are confined,then the electron must be the opposite effect?
beefpatty Posted February 16, 2013 Posted February 16, 2013 The electron is fundamental, i.e. it is not made of quarks.
derek w Posted February 16, 2013 Author Posted February 16, 2013 The electron is fundamental, i.e. it is not made of quarks. If digging a hole creates a pile of dirt,that does not infer that a pile of dirt is made of holes. I am not inferring that electrons are made of quarks.
beefpatty Posted February 16, 2013 Posted February 16, 2013 Sorry, by "opposite effect" I thought you meant 2 down and 1 up quark.
Przemyslaw.Gruchala Posted February 17, 2013 Posted February 17, 2013 (edited) I am not inferring that electrons are made of quarks. Then you should have no problem explaining how proton is converted to neutron and positron in beta decay+. http://en.wikipedia.org/wiki/Beta_decay And how proton that received electron is also converted to neutron in electron capture. http://en.wikipedia.org/wiki/Electron_capture Edited February 17, 2013 by Przemyslaw.Gruchala

derek w Posted February 18, 2013 Author Posted February 18, 2013 quote:- Earlier RHIC results suggested that when gold nuclei collide head-on their kinetic energy dissociates many nucleons and forms the hot,dense plasma of quarks and gluons,which must immediately begin to expand and cool.The hot plasma lasts only 10^-23 seconds,and only when the plasma cools sufficiently do the quarks and gluons "freeze out",leaving a spray of thousands of elementary particles carrying the signature of the hot,dense plasma that led to their production. (end quote.) Question, what is meant by "signature of the hot,dense plasma that led to their production"?
swansont Posted February 18, 2013 Posted February 18, 2013 The particles you produce are dependent on the energy and charge available that created the plasma.

Thanks Swansont for your reply. Edited February 19, 2013 by derek w
derek w Posted February 20, 2013 Author Posted February 20, 2013 Question is the weak force an accumulative force?
SamBridge Posted February 21, 2013 Posted February 21, 2013 If you just study particle physics more you will fine many physicists wanted some simple way to create a universal set of particles to describe all other particles and failed, so far there's no proof. The closest thing is string theory and it has no direct observable evidence.

Their work was immediately placed to speculations.. The closest thing is string theory and it has no direct observable evidence. You must be kidding..
derek w Posted February 21, 2013 Author Posted February 21, 2013 My understanding is that particles are thought of as wave packets,and that interaction changes the wave packets.
Przemyslaw.Gruchala Posted February 21, 2013 Posted February 21, 2013 (edited) My understanding is that particles are thought of as wave packets,and that interaction changes the wave packets. There are needed at least positive wave and negative wave. If they overlap, we detect neutral object. Otherwise charge must be hidden variable. Property of particle. But such model doesn't explain how two gamma photons are producing electron and positron. Property is automagically split.. It's like splitting 1 cent in finances...

In a 4-dimensional space,any point in 3-dimensional space can be described as oscillating in the 4th dimension. backward time wave packets,forward time wave packets,or 50% forward 50% backward,or 60% forward 40% backward etc.

And antiproton is proton that travels back in time? And pion+ is pion-, muon+ is muon-, tau+ is tau- etc that all travels back in time than their opposite electric charge equivalents.. ?

That's what you get of you apply time reversal to the particle, with CPT as a good symmetry.
