Abstract

We continue our exploration of the nearly Peccei-Quinn symmetric limit shared by common singlet extensions of the minimal supersymmetric standard model. This limit has been established as a viable framework for studying subelectroweak scale dark matter phenomenology and has interesting and direct connections to new exotic Higgs decay physics. We present analytic calculations to motivate the important phenomenological features mentioned above. We also discuss benchmark points in this model framework that accommodate the observed Galactic center gamma-ray excess. We emphasize connections between phenomenology of dark matter direct detection and indirect detection, and new exotic decay channels for the 125 GeV Higgs boson. We conclude by identifying two benchmark modes of exotic Higgs decays for h\ensuremath→\ensuremathτ⁺\ensuremathτ^\ensuremath-)E_T and h\ensuremath→bb)E_T final states and estimate their sensitivity prospects at the LHC.
