Supersymmetric SO(10) with SU(2)_L X SU(2)_R X SU(4)_C Intermediate Gauge Symmetry
arXiv:hep-ph/9712424
Abstract
In recent analyses the existence of $SU(2)_L\times\SU(2)_R\times\SU(4)_C(g_{2L}\ne g_{2R})$ intermediate gauge symmetry has been ruled out in SUSY SO(10) model at one-loop level, although the left-right symmetric intermediate gauge group has been shown to exist with certain light scalar superfields near 1 TeV.We show,how the asymmetric gauge group is allowed with an intermediate scale GeV by including two-loop and threshold effects.
