Confronting Recent Results from Selected Direct and Indirect Dark Matter Searches and the Higgs Boson with Supersymmetric Models with Non-universal Gaugino Masses

TL;DR

This paper explores supersymmetric models with non-universal gaugino masses from mixed SU(5) representations, analyzing their dark matter signatures and confronting predictions with experimental data, highlighting the viability of mixed models over singlet ones.

Contribution

It introduces and studies a class of supersymmetric models with mixed gaugino masses from multiple SU(5) representations, assessing their compatibility with experimental constraints.

Findings

No singlet models satisfy Higgs mass and relic density constraints.

Mixed models can fulfill Higgs and relic density requirements.

Future XENON 1t can potentially detect or exclude these models.

Abstract

In this paper we study a class of supersymmetric models with non-universal gaugino masses that arise from a mixture of SU(5) singlet and non-singlet representations, i.e. a combination of \textbf{1}, \textbf{24}, \textbf{75} and \textbf{200}. Based on these models we calculate the expected dark matter signatures within the linear combination \textbf{1} $\oplus$ \textbf{24} $\oplus$ \textbf{75} $\oplus$ \textbf{200}. We confront the model predictions with the detected boson as well as current experimental limits from selected indirect and direct dark matter search experiments ANTARES respective IceCube and XENON. We comment on the detection/exclusion capability of the future XENON 1t project. For the investigated parameter span we could not find a SU(5) singlet model that fulfils the Higgs mass and the relic density constraint. In contrary, allowing a mixture of \textbf{1} $\oplus$ \textbf{24} $\oplus$ \textbf{75} $\oplus$ \textbf{200} enables a number of models fulfilling these constraints.
