摘要

The process of unification within a supersymmetric left-right (SUSY L-R) model embedded in SO(10)is parametrized in terms of two intermediate scales (one at which L-R symmetry is broken and a second one at which supersymmetry breaks down to the standard model), the numbers of fermion families (F) and scalar multiplets (S),and the value of the strong coupling (#alpha#_(0s)),which we take to be between 0.110 and 0.130. The analysis is carried out at two-loop level and analytical expressions for the first-order case are also given. We compare the results of this analysis with those obtained for SUSY SU(5) and L-R SO(10), among which similar analyses have revealed significant differences in the structure of unification within these models. Unlike L-R SO(10), it is found that the Higgs contribution is indispensable to attain unification. It also turns out that a two-intermediate-scale scenario allows more in the actual values of these scales constrained by unification.
