Muon g-2 and Dark Matter in the NUGM + NUHM2 model

Abstract

We analyze the NUGM + NUHM2 model and study the implications of recent experimental constraints on the parameter space of this model. We also explore the nature of dark matter in this model and present the parameter space characterized by various compositions of the neutralino. The region of the parameter space that satisfies the observed deviation in the anomalous magnetic moment of the muon is explored more rigorously. We also present results corresponding to the production cross section and decay widths of a light CP-even Higgs boson and observe that there is a narrow region of the parameter space corresponding to a light stau which explains the observed deviation in the muon g-2 and also leads to enhancement in the Higgs production and decay widths.
