Homework Statement


Hey guys, so I'm new to Feynman diagrams, and I have a few to draw but i'll start with the first one.

I'm being asked to draw the following process: [itex]\pi^{0}[/itex](uu* or bb*)[itex]→\gamma +\gamma[/itex]. I have to "clearly label each quark, lepton and boson, and say which fundamental force is involved".


Homework Equations



None

The Attempt at a Solution



So I have no idea what to do with this. Ive done some reading about Feynman diagrams but i dont know how to work with individual quarks...

If, instead, you were asked to draw the Feynman diagram for electron-positron annihilation, i.e.,
$$e^- + e^+ ~\to~ \gamma + \gamma ~,
$$are you be able to do that?

If not, then... which textbook(s) are you learning from?
