The radiative electroweak symmetry breaking, the unification ofthird-generation Yukawa couplings, and flavor-changing rare decay areinvestigated in two types of supersymmetric SO(10) scenarios taking intoaccount of the effects of neutrino physics, i.e. the observed large generationmixing and tiny mass scale. The first scenario is minimal, includingright-handed neutrinos at intermediate scale with the unification ofthird-generation Yukawa couplings. Another is the case that the large mixing ofatmospheric neutrinos originates from the charged-lepton sector. Under theSO(10)-motivated boundary conditions for supersymmetry-breaking parameters,typical low-energy particle spectrum is discussed and the parameter space isidentified which satisfies the conditions for successful radiative electroweaksymmetry breaking and the experimental mass bounds of superparticles. Inparticular, the predictions of the bottom quark mass and the b \to s gammabranching ratio are fully analyzed. In both two scenarios, new types ofradiative electroweak symmetry breaking are achieved with the effects ofneutrino couplings. The Yukawa unification becomes compatible with the bottomquark mass and the experimental constraints from flavor-violating rareprocesses, and the hierarchical superparticle mass spectrum is obtained.Comment: 59 page
