Neutralino-hadron scattering in the NMSSM

TL;DR

This paper explores neutralino-hadron scattering in the NMSSM, updating parameter scans with recent experimental constraints, and finds that cross sections are smaller than in the CMSSM but still detectable for bino-like neutralinos.

Contribution

It provides the first comprehensive scan of the NMSSM parameter space considering recent experimental data and updated quark sigma commutator values.

Findings

Smaller spin-independent cross sections than in CMSSM.

Detection feasible for bino-like neutralinos.

Constraints from WMAP and LHC are incorporated.

Abstract

We provide a scan of the parameter space for neutralino-hadron scattering in the next-to-minimal supersymmetric standard model using an updated value for the strange quark sigma commutator. These results also take into account constraints from WMAP data on the relic density and new constraints from the Large Hadron Collider. We find that the resultant spin-independent cross sections are smaller in magnitude than those found in recent results obtained within the constrained minimal supersymmetric standard model, yet still great enough to feasibly allow for detection in the case of bino-like neutralinos.
