1. The problem statement, all variables and given/known data
I have come across the following scattering : ee >e+e+ Does anyone know the name of this scattering ? Do you know of any book describing simililar lepton scatterings? Thank you 2. Relevant equations 3. The attempt at a solution

can you see charge conservation here?

No charge conservation
Do you think this might be a typo? I will completely honest with you , this is a question from a homework :(look the attachement) if there is a typo then should the process ee+  > ee+ be considered an exotic scattering?

ee >e+e+ scattering
oh no,from which book you have gotten that?
ee+  > ee+,this specially is related to bhabha scattering.this does hold.By the way,what is exotic here?

If it is the ee+  > ee+ process shouldn't the question also clarify if it is spinless or not andrien ?

what do you mean by spinless.electron and positron can have it's spin along a certain chosen z axis in the same direction which is in fact a requirement of bhabha scattering!

well, i have just entered the field of particle physics ,and i don't know many things.
Thanks for the replies

The image i uploaded as i said , was taken from a homework assighnement.I don't know where he found it ,maybe a book came from an alternative universe through a wormhole,where the charge conservation law doesn't hold ,and so my teacher thought it was from our own universe.
