Quark-lepton Yukawa unification at lower mass scales
- International Centre for Theoretical Physics, Trieste (Italy)
In the nonsupersymmetric two-Higgs-doublet standard model, we find {ital t}-{ital b}-{tau} Yukawa unification consistent with the CERN LEP data, experimental values of {ital m}{sub {ital b}}, {ital m}{sub {tau}}, and {ital m}{sub {ital t}}=160{endash}190 GeV at lower mass scales: {ital M}{sub {ital C}}{approx_equal}3{times}10{sup 8}{endash}3{times}10{sup 9} GeV. We also show how such quark-lepton unification scales can be reconciled with SU(2){sub {ital L}}{times}SU(2){sub {ital R}}{times}SU(4){sub {ital C}} intermediate breaking in SO(10) including threshold and gravitational corrections. {copyright} {ital 1996 The American Physical Society.}
