Evidence for unification of couplings

  1. Oct 18, 2011 #1
    Hi there - I'm looking for a reference on the issue of whether the three fundamental couplings unify. The most recent reference I have is from 1993, at which time it looked like the odds were against unification, but does anyone know a more recent reference? Thanks!

    The usual claim is that the couplings fail to unify in the standard model, but they do in the MSSM.
