File talk:Feynmann Diagram Gluon Radiation.svg

It strikes me that the feynman diagram for electron - positron annihilation is wrong.

The arrow on the positron line is in the opposite direction and the arrow on the anti quark is in the opposite direction. If we reverse these two arrows it then seems to make sense.

Or have I missed something?

Positrons have their time arrows pointing backwards in times, think of positrons as electrons going back in time. Also, I dont think colour charge is conserved on this diagram, a free gluon cannot be formed by such a process, should it be terminated? —Preceding unsigned comment added by 80.235.132.32 (talk) 12:07, 17 May 2008 (UTC)
 * Then it seems it would make more sense if the +/- symbols were remove from the *trons and quarks. If the arrow points backwards in time, then you are the either the "anti" particle or the regular particle going back in time. njaard (talk) 05:25, 6 October 2008 (UTC)

I think it's important to note that the diagram pictured is a Feynman diagram. Why does this page refer to Feynmann?
