Impact of DM direct searches and the LHC analyses on branon phenomenology

TL;DR

This paper evaluates how recent dark matter direct detection experiments and LHC collider analyses constrain branon models, highlighting that current collider data already surpass older experiments in constraining heavy branons.

Contribution

It provides updated constraints on branon dark matter models using recent experimental data from direct detection and collider experiments, emphasizing the improved sensitivity of LHC results.

Findings

LHC measurements are more constraining than previous TEVATRON and LEP data for heavy branons.

Recent CDMS data favors specific regions of the branon parameter space.

Collider constraints significantly restrict the viable parameter space for branon dark matter.

Abstract

Dark Matter direct detection experiments are able to exclude interesting parameter space regions of particle models which predict an important amount of thermal relics. We use recent data to constrain the branon model and to compute the region that is favored by CDMS measurements. Within this work, we also update present colliders constraints with new studies coming from the LHC. Despite the present low luminosity, it is remarkable that for heavy branons, CMS and ATLAS measurements are already more constraining than previous analyses performed with TEVATRON and LEP data.
