Implications of CDMS II result on Higgs sector in the MSSM

TL;DR

This paper examines how recent CDMS-II dark matter detection results influence the Higgs sector predictions within the MSSM, considering updated nucleon content data and various neutralino mixing scenarios.

Contribution

It provides new insights into the Higgs mass predictions and dark matter interactions in the MSSM based on recent experimental and lattice simulation data.

Findings

Heavy Higgs mass constrained in Bino-Higgsino neutralino scenario

Higgs sector not constrained in Wino-Higgsino scenario

Dark matter detection rates dominated by Higgs exchange processes

Abstract

We study implications of two dark matter candidate events at CDMS-II on the neutralino dark matter scenario in the supersymmetric standard model, in light of the recent lattice simulation on the strange quark content of a nucleon. The scattering rate of neutralino-nucleon is dominated by Higgs exchange processes and the mass of heavy Higgs boson is predicted for the neutralino of Bino-Higgsino mixing state. In the case of Wino-Higgsino mixing, the Higgs sector may not be constrained.
