Answer 1

Hey !

______________________________

There are two important differences between electron-electron and electron-positron scattering.

Through the photon has no charge, its interaction with a charged particle

Answer 2

Hey....

Why does an electron react differently to a virtual photon in the interaction between two electrons and between an electron and a positron?

Answer :-

For the interaction between say and electron and a positron there correspond many....

Feynman diagram of splitting the particles of this shows it very clearly with examples...

Thank you
