Arnaud Antoine ANDRIEU Posted June 20, 2013 Share Posted June 20, 2013 hello Is there a Feynman diagram which includes all particles with by example electron, quark, pion, kaon, ...in one? Thanks I mean a Feynman diagram that draws all the particles with their way of all arrows in the same pattern. A Feynman diagram atom ; It is possible to draw?

ajb Posted June 20, 2013 Share Posted June 20, 2013 I am not really sure what you are asking here. You want a Feynman diagram with all the standard model particles going in and out? Link to comment Share on other sites More sharing options...

Hi ajb, yes a Feynman diagram which closes the loop of atom, with the path of the in out ions There is better diagram than Feynman diagram?

ajb Posted June 20, 2013 Share Posted June 20, 2013 It is still not very clear exactly what you are looking for. One technical issue here is that Feynman diagrams are graphical representations of propagators and these are used to construct S-matrices. All this has to do with scattering rather than bound states like atoms. Link to comment Share on other sites More sharing options...

All this has to do with scattering rather than bound states like atoms. yes forget the ionic bond.... Rather it is possible to draw the scattering of one atom with one S-matrices diagram? In fact I would like to reunite on a same Feynman diagram all kaon and pion. It is possible? thank you Link to comment Share on other sites More sharing options...
ajb Posted June 20, 2013 Share Posted June 20, 2013 yes forget the ionic bond....

Anyway, you can write down diagrams for particles colliding with atoms. Though I think people are usually interested in either the interactions with the electrons in the shells or the nucleus rather than both. Link to comment Share on other sites More sharing options...
Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 You need all the diagrams to a given order to get a reasonable calculation of the scattering amplitude. It interested me. it is expressed in eV /c ² ? Anyway, you can write down diagrams for particles colliding with atoms. just to link all pion in the same Feynman diagram (pion - antipion with the quark path) Link to comment Share on other sites More sharing options...
ajb Posted June 20, 2013 Share Posted June 20, 2013 That would be a mass. Cross sections are in units of length squared (area). Amplitudes are probabilites. Link to comment Share on other sites More sharing options...
Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 That would be a mass. Cross sections are in units of length squared (area). Amplitudes are probabilites. The amplitude isn't based on eV /c ² ? or which one? What is the best diagram used to explain the interaction of decay particles? and also their positions in the atom (quark, electron)? Thank you ajb Link to comment Share on other sites More sharing options...
ajb Posted June 20, 2013 Share Posted June 20, 2013 What is the best diagram used to explain the interaction of decay particles? and also their positions in the atom (quark, electron)?You need to be more specific, but the tree level diagrams for simple decays are avaliable through google.

Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 the tree level diagrams for simple decays are avaliable through google. Which one please? Do you want to talk about Feynman? Simple question... Can you give me the best you got? Link to comment Share on other sites More sharing options...
ajb Posted June 20, 2013 Share Posted June 20, 2013 Negative beta decay for example Link to comment Share on other sites More sharing options...
Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 (edited) Negative beta decay for example Easy. In a few days I'll show you mine which includes all diagrams like this one in in one. I will meet all leptons (electron - tau - muon - quark) I will meet all antileptons I will meet all neutrinos I will meet all antineutrinos I will meet all bosons W - Z - g I will meet the boson H And I will meet the photon Edited June 20, 2013 by Arnaud Antoine ANDRIEU Link to comment Share on other sites More sharing options...

Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 yes sorry, but it changes nothing Do you know how am I going to do all particles in the same diagram? when I say all pions and all kaons in the same diagram, it is with the + the - the ° and the anti° Link to comment Share on other sites More sharing options...
ajb Posted June 20, 2013 Share Posted June 20, 2013 I await your diagrams. Link to comment Share on other sites More sharing options...
Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 I await your diagrams. Ok. You can count on me. Just 24/48h Good day if you want I can already make all pions and kaons in ten minutes with paint .. I come back I based this model with that one ---> fermionic_model_ but it is a bit wrong (the pion+ is not in the right place) _______________________________________________________________________ hi, I did not draw boson. But you can already in indentify two (boson) in the case of the kaon box which is between d and s for W- and between anti-si and anti-d. I let you imagine the rest, nuon, boson H with top quark ... image link --> http://blogs.scienceforums.net/ArnaudAntoineANDRIEU/files/2013/06/atom_a.png I'll give you the complete diagram but not today. You can share it as you want. Link to comment Share on other sites More sharing options...

Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 It does not look like we conservation of electrc charge here. ?? show me what you want to mean with feynman diag .. charge A and charge B ? it is for the follow (the photon use charge B with annihilation of neutrino and antineutrino) Link to comment Share on other sites More sharing options...

Arnaud Antoine ANDRIEU Posted June 20, 2013 Author Share Posted June 20, 2013 e^{+} -> \bar(u) if you make one decay before e-, then you product W- and gluon the photon need the complet quark (e- --> e+) Wait the follow in two day I'll make the brayon The diagram is a string. If you break the chain(decay) you created some bosons. Link to comment Share on other sites More sharing options...
Arnaud Antoine ANDRIEU Posted June 21, 2013 Author Share Posted June 21, 2013 (edited) hello, I am drawing this one from wiki https://en.wikipedia.org/wiki/File:Kaon-decay.png I come back Feynman diagrams has become obsolete.. this is a good scoop that, right? It's name is atom PCB but it's better to say atom A because of its shape In the upper chamber of the pyramid is the atomic number.....if you add one more quark at your meson then you have a neutron. And if again you add a new quark with neutron, then you get a proton. I await your diagrams. then, not bad, no?

swansont Posted June 22, 2013 Share Posted June 22, 2013 at least I'm sure to find my diagrams on the books of physic by next fall. No, this is not likely at all. Your diagrams make no sense and you have not explained how they are used to do any predictions or explain any reactions. As ajb has noted already, you violate conservation of charge at various places. It also looks like you violate conservation of energy and/or momentum. 1 Link to comment Share on other sites More sharing options...
