Exploring SUSY light Higgs boson scenarios via dark matter experiments

TL;DR

This paper investigates how supersymmetric light Higgs boson models can be tested through dark matter experiments, focusing on relic density, gamma-ray, and antiproton signals, while remaining consistent with current detection constraints.

Contribution

It explores dark matter phenomenology in nonuniversal Higgs mass scenarios, highlighting the potential for indirect detection signals compatible with existing experiments.

Findings

Most of the A-pole region can produce detectable gamma-ray signals.

Antiproton signals from these scenarios are potentially observable.

Models remain consistent with recent XENON100 and CDMS-II data.

Abstract

We examine the dark matter phenomenology in supersymmetric light higgs boson scenarios, adapting nonuniversal Higgs masses at the gauge coupling unification scale. The correct relic density is obtained mostly through the annihilation into a pseudoscalar $A$, which gives high values for the self-annihilation cross-section at present times. Our analysis shows that most part of the $A$ pole region can produce detectable gamma-rays and antiproton signals, and still be compatible with with recent direct detection data from XENON100 and CDMS-II.
