SU(5) grand unification in pure gravity mediation

We discuss the proton lifetime in pure gravity mediation models with nonuniversal Higgs soft masses. Pure gravity mediation offers a simple framework for studying SU(5) grand unified theories with a split supersymmetrylike spectra. We find that for much of the parameter space gauge coupling unification is quite good leading to rather long lifetimes for the proton. However, for m3/2∼60TeV and tanβ∼4, for which gauge coupling unification is also good, the proton lifetime is short enough that it could be in reach of future experiments.
