Neutrino Scattering

  1. Jul 7, 2011 #1
    Hey...i'm studying the reaction neutrino+antineutrino -> W(+) + W(-)
    but i dont understand which are the relevant f. diagrams at first order (semiclassic approximation). Does anyone know which are???

    thank you

    At tree level I'd say there's just one. In the crossed channel: νe + W- → e- → νe + W-

    Shouldn't there also be a contribution from an s-channel Z?
