Embedding the 125 GeV Higgs boson measured at the LHC in an effective MSSM: possible implications for neutralino dark matter

TL;DR

This paper explores how the 125 GeV Higgs boson observed at the LHC fits within an effective MSSM framework and examines the implications for neutralino dark matter, considering experimental constraints and detection prospects.

Contribution

It introduces two scenarios of embedding the Higgs boson in an effective MSSM and analyzes their impact on neutralino dark matter properties and detection rates.

Findings

Certain MSSM parameter regions are consistent with the Higgs mass and collider data.

Neutralino relic abundance can match cosmological observations in these scenarios.

Predicted detection rates vary significantly depending on model parameters.

Abstract

We analyze the phenomenological consequences of assuming that the 125 GeV boson measured at the LHC coincides with one of the two CP-even Higgs bosons of an effective Minimal Supersymmetric extension of the Standard Model at the electroweak scale. We consider the two ensuing scenarios and discuss critically the role of the various experimental data (mainly obtained at colliders and at B-factories) which provide actual or potential constraints to supersymmetric properties. Within these scenarios, properties of neutralinos as dark matter particles are analyzed from the point of view of their cosmological abundance and rates for direct and indirect detections.
