TeV scale partial mirage unification and neutralino dark matter

TL;DR

This paper explores a TeV scale supersymmetric scenario where gluino and wino masses are degenerate, addressing the little hierarchy problem and proposing a bino-higgsino mixture as a viable dark matter candidate.

Contribution

It introduces a partial mirage unification model with specific gaugino mass relations that resolve the little hierarchy problem and produce a suitable dark matter candidate.

Findings

Gluino and wino masses are degenerate around 1 TeV.

The scenario alleviates the little hierarchy problem.

The lightest superparticle is a bino-higgsino mixture with correct relic density.

Abstract

We study the TeV scale partial mirage unification scenario, where the gluino and wino masses are degenerate around a TeV scale, but the bino mass is not degenerate. This scenario has phenomenologically interesting aspects. First, because of the degeneracy between the gluino and wino masses, this scenario does not have the little hierarchy problem, that is, the higgisino mass is around 150 GeV. The lightest superparticle is a mixture of the bino and higgsino, and can lead to a right amount of thermal relic density as a dark matter candidate.
