On suppressing the Higgsino-mediated proton decay in SUSY SO(10) GUT’s
نویسنده
چکیده
Using the freedom in SO(10) GUT’s one can generalize the existing models without changing the mass spectrum of fermions to obtain a significant suppression of proton decay resulting from the dimension 5 operators with ∆B 6= 0. In some limiting cases, these operators can be made negligible compared to dimension 6 operators resulting from the heavy gauge bosons exchange. email: [email protected]

In supersymmetric Grand Unified Theories, proton decay mediated by the color–triplet higgsino is generally problematic and requires some fine–tuning of parameters. We present a mechanism which naturally suppresses such dimension 5 operators in the context of SUSY SO(10). The mechanism, which implements natural doublet–triplet splitting using the adjoint higgs, converts these dimension 5 operato...
متن کاملProton Decay in the Semi-Simple Unification
Semi-simple unification is one of a model which naturally solves two difficulties in the supersymmetric grand unification theory: doublet-triplet splitting problem and suppression of dimension 5 proton decay. We analyzed the dimension 6 proton decay of this model using perturbative analysis at the next-to-leading order. The life time of proton is 3×1034 1035 years for wide range of SUSY breakin...
متن کاملMinimal So(10) Unification
It is shown that the doublet-triplet splitting problem can be solved in SO(10) using the Dimopoulos-Wilczek mechanism with a very economical Higgs content and simple structure. Only one adjoint Higgs field is required, together with spinor and vector fields. The successful SUSY GUT prediction of sin 2 θ W is preserved, with the threshold corrections due to superheavy Higgs states being only of ...
متن کاملNew contribution to dimension five operators on proton decay in anomaly mediation scenario
In supergravity, effective superpotential relevant to dimension five operators on proton decay processes also leads to supersymmetry breaking terms among sfermions, dimension four operators. These dimension four operators induce the dimension five operators through 1-loop diagrams dressed by gauginos. We find that, in a class of models with the anomaly mediation, the 1-loop contributions can be...
متن کاملProton Decay and Realistic Models of Quark and Lepton Masses
It is shown that in realistic SUSY GUT models of quark and lepton masses both the proton decay rate and branching ratios differ in general from those predicted in the minimal SU(5) supersymmetric model. The observation of proton decay, and in particular the branching ratio B[(p → π+ν)/(p → K+ν)], would thus allow decisive tests of these fermion mass schemes. It is shown that the charged lepton ...
