Dark matter in GUT inspired $Z^\prime$ portal scenarios

TL;DR

This paper investigates dark matter models inspired by grand unification theories with $Z^\prime$ portals, analyzing how direct detection constraints limit the parameter space and impact the viability of thermal dark matter scenarios.

Contribution

It introduces a simplified GUT-inspired $Z^\prime$ portal dark matter model and demonstrates how combined direct detection constraints effectively restrict its parameter space.

Findings

Combined direct detection constraints significantly limit the model's parameter space.

Thermally produced dark matter scenarios face stringent bounds in this framework.

Complementary constraints enhance the ability to test and refine dark matter models.

Abstract

We consider simple dark matter extensions of the standard model in $Z^\prime$ portal scenarios inspired by grand unification theory constructions and we study the phenomenology of such models by considering Spin Dependent and Spin Independent direct detection constraints, confronting the canonical thermally produced dark matter scenario and we show that in this simple framework the combination and the complementary of these constraints is a powerful tool to derive stringent bounds and to reduce the viable parameter space of the model.
