Proton Decay in the Semi-Simple Unification

High Energy Physics - Phenomenology 2009-11-07 v1

Abstract

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 \times 10^{34} - 10^{35} years for wide range of SUSY breaking parameters, and there is an intriguing possibility of observing proton decay signals in the next-generation water Cherenkov detectors such as Hyper-Kamiokande and TITAND. Several uncertainties in this prediction are also discussed.
