A bstract We consider two distinct classes of Yukawa unified supersymmetric SO (10)
models with non-universal and universal soft supersymmetry breaking (SSB) gaugino
masses at M GUT. In both cases, we assume that the third family SSB sfermion masses at M
GUT are different from the corresponding sfermion masses of the first two families (which are
equal). For the SO (10) model with essentially arbitrary (non-universal) gaugino masses at M
GUT, it is shown that tb-τ Yukawa coupling unification is compatible, among other things …
