Radiative corrections to sin2 θ W exp in theS U(5) model

  • Published:

Abstract

We compute perturbatively in theSU(5) grand unification theory the radiative corrections to sin2 θ W O through a phenomenological weak mixing angle, sin2 θ W exp(q 2), defined in thev μ e elastic scattering. We essentially recover the results obtained by using the renormalization group analysis.
