Title: A minimal supersymmetric SU(5) missing-partner model

Abstract

We explore a missing-partner model based on the minimal SU(5) gauge group with 75, 50 and 50¯ Higgs representations, assuming a super-GUT CMSSM scenario in which soft supersymmetry-breaking parameters are universal at some high scale Min above the GUT scale MGUT. We identify regions of parameter space that are consistent with the cosmological dark matter density, the measured Higgs mass and the experimental lower limit on τ(p → K+ν). These constraints can be satisfied simultaneously along stop coannihilation strips in the super-GUT CMSSM with tanβ ~ 3.5–5 where the input gaugino mass m1/2~15–25 TeV, corresponding after strong renormalization by the large GUT Higgs representations between Min and MGUT to mLSP,mt~1 ~ 2.5–5 TeV and mg~ ~ 13–20 TeV, with the light-flavor squarks significantly heavier. We find that τ(p → K+ν) ≲ 3 × 1034 years throughout the allowed range of parameter space, within the range of the next generation of searches with the JUNO, DUNE and Hyper-Kamiokande experiments.
