A-V Couplings for Antiparticles

  1. May 10, 2012 #1
    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 + νe → e + νe and e + νe → e + νe 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(eνe) = 3 σ(eνe).
