GUT and Feynman rules

  1. Jan 9, 2013 #1
    Hi all,
    Having learnt much about technicalities in Grand Unified Theory, I have known that it's basically pursuing the belief that coupling constants of all interactions converge to the same value.
    My question is, do Feynman rules still hold in this theory (b/c each type of interaction involves different propagator, vertex factor, etc.)? or have the physicists already accounted for it, then how?
    Lastly, is GUT suggesting given same before and after energies in a relativistic frame (KE is not trivial), the identity of those parent/daughter particles are irrelevant because they'd couple the same way with same lifetime&cross section (at very high energy limit)?

    Thanks in advance!
