A-V Couplings for Antiparticles

roughgemjd

Hey everyone,
I was wondering how the ca and cv vary for weak interactions with antiparticles. It seems that they must be different. Perhaps this is incorrect, but if this is the case I am not sure how there is a difference between e eantineutrino-> e eantineutrino differs from e eneutrino->e eneutrino

Thanks in advance!

e + ν_e → e + ν_e and e + ν_e → e + ν_e are basically the same reaction. You can get one from the other by going to the crossed channel. For this reason there's a simple relationship between their cross-sections: σ(eν_e) = 3 σ(eν_e).
