Autonomous Renormalization of the One-Loop Effective Potential and a 2 Tev Higgs in SU(2)xU(1)

Abstract

Branchina et al and Consoli have recently shown that the one-loop effective potential (1LEP) of massless lambda-phi**4 theory can be renormalized in two distinct ways. One of these is the conventional renormalization of Coleman and Weinberg. The other requires an infinite wavefunction renormalization, and is very similar to the "autonomous" renormalization of the Gaussian effective potential. We apply the "autonomous" renormalization to the 1LEP of the SU(2)x U(1) electroweak theory with zero bare Higgs mass. The predicted physical Higgs mass is 1.9 TeV.
