LHC Signals of Non-Custodial Warped 5D Models

TL;DR

This paper explores how modified warped extra-dimensional models can produce detectable signals at the LHC, especially involving third-generation quarks, without conflicting with electroweak precision constraints.

Contribution

It introduces a class of non-custodial warped 5D models with modified IR brane geometry, enabling TeV-scale Kaluza-Klein excitations compatible with precision tests.

Findings

Third-generation quark signals are most promising for detection.

Electroweak and strong KK gauge bosons can be produced at the LHC.

Models evade electroweak constraints while predicting new TeV-scale particles.

Abstract

We study the implications at the LHC for a recent class of non-custodial warped extra-dimensional models where the AdS_5 metric is modified near the infrared brane. Such models allow for TeV Kaluza-Klein excitations without conflict with electroweak precision tests. We discuss both the production of electroweak and strong Kaluza-Klein gauge bosons. As we will show, only signals involving the third generation of quarks seem to be feasible in order to probe this scenario.
