# GUT Models at Current and Future Hadron Colliders and Implications to Dark Matter Searches

## TL;DR

This paper investigates GUT-inspired models at current and future colliders by analyzing dilepton data to set bounds on $Z'$ boson masses and explores implications for dark matter detection.

## Contribution

It provides the first comprehensive limits on $Z'$ masses from GUT models at multiple collider energies and discusses their relevance to dark matter searches.

## Key findings

- 95% C.L. bounds on $Z'$ masses at various collider energies.
- Projected sensitivities for future colliders up to 100 TeV.
- Implications for dark matter detection experiments.

## Abstract

Grand Unified Theories (GUT) offer an elegant and unified description of electromagnetic, weak and strong interactions at high energy scales. A phenomenological and exciting possibility to grasp GUT is to search for TeV scale observables arising from Abelian groups embedded in GUT constructions. That said, we use dilepton data (ee and $\mu\mu$) that has been proven to be a golden channel for a wide variety of new phenomena expected in theories beyond the Standard Model to probe GUT-inspired models. Since heavy dilepton resonances feature high signal selection efficiencies and relatively well-understood backgrounds, stringent and reliable bounds can be placed on the mass of the $Z^{\prime}$ gauge boson arising in such theories. In this work, we obtain 95\% C.L. limits on the $Z^{\prime}$ mass for several GUT-models using current and future proton-proton colliders with $\sqrt{s}= 13~{\rm TeV},\, 33~{\rm TeV},\,{\rm and}\, 100$~TeV, and put them into perspective with dark matter searches in light of the next generation of direct detection experiments.
