Light Neutralino Dark Matter Scenario in Supersymmetric Four-Higgs Doublet Model

TL;DR

This paper explores a supersymmetric four-Higgs doublet model that can simultaneously explain dark matter detection signals, relic abundance, and collider anomalies.

Contribution

It introduces a novel four-Higgs doublet framework that accounts for dark matter signals and collider anomalies within a supersymmetric context.

Findings

The model explains DAMA and CoGeNT signals simultaneously.

It is consistent with observed dark matter relic abundance.

It also accounts for the CDF Wjj anomaly.

Abstract

We examine a possibility to explain the signals of dark matter direct detection from DAMA and CoGeNT experiments, under the framework of supersymmetric extension of the standard model. For this purpose, we introduce four Higgs doublet fields and assume that one pair of Higgs fields which have very small vacuum expectation values gives sizable effects for annihilation and scattering processes of dark matter. We show that the preferred parameter regions for DAMA and CoGeNT results can be simultaneously explained by supersymmetric four-Higgs doublet model with the parameters consistent with the observed value of dark matter relic abundance. The extra Higgs fields introduced as an explanation of the light dark matter scenario also explain the Wjj anomaly reported by CDF.
