Feynman diagram for radiative transition

samedi 29 mars 2014

Hi,

I was just trying to draw a Feynman diagram for ψ' to [itex]χ_{c}[/itex] states.

So we have a electromagnetic transition.



I feel tempted to just have c and [itex]\bar{c}[/itex] coming in and letting a γ leave from one of the legs. But that looks like an incomplete Feynman diagram to me. Maybe I have to get two photons out?



Can someone help me with this please!
