The NMSSM at the Cosmic Frontier for Snowmass 2013

TL;DR

This paper explores the Next-to-Minimal Supersymmetric Standard Model (NMSSM) in the context of dark matter detection, analyzing neutralino compositions and prospects for future experiments following the Higgs discovery.

Contribution

It provides a detailed analysis of NMSSM dark matter candidates and their detectability in current and future experiments, highlighting the parameter space consistent with relic abundance.

Findings

Neutralino can be singlino or bino dominated for correct relic abundance.

Wino and higgsino DM have lower relic abundance but are detectable at IceCube.

Future direct detection experiments will cover most of the NMSSM parameter space.

Abstract

We examine the NMSSM at the cosmic frontier in the post Higgs discovery world. For DM relic abundance consistent with measurement, we find the neutralino can either be singlino or bino dominated. Wino and higgsino DM generally yield a lower abundance, but offer opportunities of detection at IceCube. For both cases, future SI direct detection experiments cover a majority of the model, including nearly all of the bino and higgsino scenarios.
