Effects of large mass fermions on Msub(x) and sin2thetasub(w)
Description
Some effects of heavy quarks and leptons are analyzed in the standard SU(5) model. We evaluate the two-loop corrections to the SU(3), SU(2), and U(1) β-functions incorporating the effects of large Yukawa couplings of the fermions to the Higgs bosons. The corrections to Msub(x) and sin2thetasub(w) are found to be small for fermion masses less than approx. equal to 240 GeV. (orig.)
