Precision measurements, dark matter direct detection and LHC Higgs searches in a constrained NMSSM

TL;DR

This paper reanalyzes the constrained NMSSM considering collider, dark matter, and B-physics constraints, evaluating detection prospects for dark matter and heavy Higgs states at the LHC.

Contribution

It provides a comprehensive reexamination of the constrained NMSSM with updated experimental constraints and assesses future detection prospects for dark matter and heavy Higgs particles.

Findings

Constraints significantly restrict the parameter space.

Dark matter detection prospects are promising in certain regions.

Heavy Higgs discovery at the LHC is feasible under specific conditions.

Abstract

We reexamine the constrained version of the Next-to-Minimal Supersymmetric Standard Model with semi universal parameters at the GUT scale (CNMSSM). We include constraints from collider searches for Higgs and SUSY particles, upper bound on the relic density of dark matter, measurements of the muon anomalous magnetic moment and of B-physics observables as well as direct searches for dark matter. We then study the prospects for direct detection of dark matter in large scale detectors and comment on the prospects for discovery of heavy Higgs states at the LHC.
