Upper limit on the proton lifetime in minimal supersymetric SU(5)

In minimal supersymmetric SU(5) models, the proton can decay through dimension 5 operators. Since this decay depends directly on the supersymmetric soft masses, it will be constrained by other observables which depend on the soft masses, such as the Higgs mass and the dark matter relic density. In this work, we will examine the upper limit on the proton lifetime in minimal supersymmetric SU(5) with constrained minimal supersymmetric (CMSSM) boundary conditions set at the grand unification scale. We perform a random scan over the variables of the (CMSSM), with of order 10(6) points, and find that the proton lifetime is within reach of JUNO and Hyper-Kamiokande's experiment.

Automated summary

In minimal supersymmetric SU(5) models, the decay of proton through dimension 5 operators, which is directly dependent on supersymmetric soft masses, is constrained by other observables. By performing a random scan over the variables of the constrained minimal supersymmetric SU(5) model, it is found that the proton lifetime can be within reach of JUNO and Hyper-Kamiokande's experiment.
