Abstract

A simple Pati-Salam SU(4) model with a low symmetry breaking scale of about 1000 TeV is presented. The analysis concentrates on calculating radiative corrections to tree-level mass relations for third generation fermions. The tree-level relation mbmτ=1 predicted by such models can receive large radiative corrections up to about 50% due to threshold effects at the mass unification scale. These corrections are thus of about the same importance as those that give rise to renormalization group running. The high figure of 50% can be achieved because one-loop graphs involving the physical charged Higgs boson give corrections to mτ-mb that are proportional to the large top quark mass. These correct..
