Title: Proton decay in the semi-simple unification.
Authors: Fujii, Masaaki, Watari, T. watari@hep-th.phys.s.u-tokyo.ac.jp
Source: Physics Letters B. Feb2002, Vol. 527 Issue 1/2, p106. 9p.
Subjects: Proton decay, Grand unified theories (Nuclear physics)
Abstract: Semi-simple unification is one of models which naturally solve 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 breaking parameters, and there is an intriguing possibility of observing proton decay signals in the next-generation water Cˇerenkov detectors such as Hyper-Kamiokande and TITAND. Several uncertainties in this prediction are also discussed. [Copyright &y& Elsevier]
