Brane-Worlds at the LHC: Branons and KK-gravitons

TL;DR

This paper investigates how Brane-World models, specifically KK-gravitons and branons, can be tested at the LHC by analyzing their production signatures and constraining their parameters using ATLAS data.

Contribution

It compares KK-graviton and branon signals at the LHC and uses recent ATLAS data to set bounds on their model parameters.

Findings

KK-graviton and branon signals can dominate depending on brane tension.

Recent ATLAS data constrains the parameter space of both phenomena.

Differences between the signatures help distinguish between models.

Abstract

We study the possibility of testing some generic properties of Brane-World scenarios at the LHC. In particular, we pay attention to KK-graviton and branon production. Both signals can be dominant depending on the value of the brane tension. We analyze the differences between these two signatures. Finally, we use recent data in the single photon channel from the ATLAS collaboration to constraint the parameter space of both phenomenologies.
