Description

Imposing the gauge coupling unification and the Higgsino-like neutralino dark matter in our Universe, we perform a parameter scan for a simple parameter set in the Minimal Supersymmetric Standard Model, namely, the universal sfermion mass ($m_0$) and the universal gaugino mass at the GUT scale ($M$). We find that sparticle masses in the range of 10-100 TeV result in the lifetime of proton decay mediated by the GUT gauge bosons that can be tested in the Hyper-Kamiokande experiment in the near future.
