# Superheavy-Higgs-scalar effects in effective gauge theories from SO(10) grand unification with low-mass right-handed gauge bosons

## Abstract

We investigate possible modifications of SO(10) predictions due to superheavy components of Higgs scalars, needed for the spontaneous symmetry breaking of the grand unified theory to effective gauge theories, where parity and SU(2){sub {ital R}} breakings are decoupled. Interesting modifications with low-mass {ital W}{sub {ital R}}{sup {plus minus}} gauge bosons are found to be possible if the superheavy masses are nondegenerate, but satisfy the Coleman-Weinberg constraint. With the single intermediate symmetry, SU(3){sub {ital C}}{times}SU(2){sub {ital L}} {times}SU(2){sub {ital R}}{times}U(1){sub {ital B}{minus}{ital L}}, even a factor of 10 nondegeneracy is found to lower the {ital W}{sub {ital R}}{sup {plus minus}} and {ital Z}{sub {ital R}} mass prediction by 4 orders, compared to earlier results, yielding {ital M}{sub {ital R}}{approx equal}100 TeV for sin{sup 2}{theta}{sub W}{approx equal}0.235. In the presence of the second intermediate symmetry, SU(3){sub {ital C}}{times}SU(2){sub {ital L}} {times}U(1){sub {ital R}}{times}U(1){sub {ital B}{minus}{ital L}}, which could survive down to {ital M}{sub {ital Z}{sub {ital R}}}{approx equal}500 GeV, we obtain 1 TeV{lt}{ital M} {sub {ital W}{sub {ital R}}}{lt}80 TeV for 0.238{gt}sin{sup 2}{theta}{sub {ital W}}{gt}0.231. The values of sin{sup 2}{theta}{sub {ital W}} can be lowered further if the nondegeneracy factor is allowed to be larger.
