# Study of dark matter physics in non-universal gaugino mass scenario

## TL;DR

This paper investigates dark matter in a non-universal gaugino mass scenario within the MSSM, highlighting how specific mass ratios naturally achieve the electroweak scale and Higgs mass, with direct detection experiments providing strong constraints.

## Contribution

It introduces a scenario with non-universal gaugino masses that naturally explains the electroweak scale and Higgs mass, and analyzes dark matter detection constraints in this context.

## Key findings

- XENON1T excludes bino or gluino lighter than 2.5 TeV with same sign gaugino and higgsino masses.
- Direct detection constraints surpass LHC search bounds when higgsino significantly contributes to dark matter.
- Relatively light higgsino is a viable dark matter candidate in this scenario.

## Abstract

We study dark matter physics in the Minimal Supersymmetric Standard Model with non-universal gaugino masses at the unification scale. In this scenario, the specific ratio of wino and gluino masses realizes the electro-weak scale naturally and achieves 125 GeV Higgs boson mass. Then, relatively light higgsino is predicted and the lightest neutral particle, that is dominantly given by the neutral component of higgsino, is a good dark matter candidate. The direct detection of the dark matter is sensitive to not only a higgsino mass but also gaugino masses significantly. The upcoming XENON1T experiment excludes the parameter region where bino or gluino is lighter than about 2.5 TeV if the higgsino and the gaugino mass parameters have same signs. We see that the direct detection of dark matter gives stronger bound than the direct search at the LHC experiment when higgsino sizably contributes to the dark matter abundance
