Hi,
a simple question on W boson vertices (and I guess field theory in general). If I have a W boson vertex for incoming particles, i.e.
W^+ ubar d and W^- u dbar
how do I change this for outgoing W's. The first interaction contains a CKM matrix element Vud and the second a Vud^*, and I want to figure out which one of them has the complex conjugate in the case of outgoing W's.
Thanks!
