That wikipedia article does have the feynman diagram for the stron interaction between a proton and a neutron. I have seen it before. So in this diagram I'm drawing, do I need to just add gluons and interactions? My reservation is that I'm supposed to be drawing the lowest order diagrams...

I know that the wikipedia diagrams aren't really correct because they label the antiparticles and have the arrows the wrong way, which isn't convention. But they're correct other than that, no? So you're saying that, for the annihilation case, the energy of the virtual photon is equal to the...

Homework Statement Determine the mass of the virtual photon in each of the lowest-order diagrams for Bhabha scattering (assume the electron and positron are at rest). What is its velocity? (Note that these answers would be impossible for real photons) Note: You can "just write down" the...

I don't "have" any other such diagrams. We have discussed this sort of interaction in detail yet.

Homework Statement Is the following reaction possible? If so, by what force? Draw (one of, if applicable)the lowest order Feynman diagrams for the process. n + n-bar --> ∏+ + ∏- + ∏0Homework Equations N/AThe Attempt at a Solution This process, it seems to me, should be possible. It...
