Graviton production with 2 jets at the LHC in large extra dimensions

TL;DR

This paper investigates the production of Kaluza-Klein gravitons in large extra dimensions at the LHC, focusing on 2 jets plus missing transverse momentum signatures, and proposes optimized jet selection cuts to distinguish signal from background.

Contribution

It introduces missing P_T-dependent jet selection cuts that improve the identification of KK graviton production signals at the LHC.

Findings

Jet selection cuts reduce background contamination.

Distributions of jets and missing P_T support graviton production evidence.

Method enhances detection prospects for large extra dimensions.

Abstract

We study Kaluza-Klein (KK) graviton production in the large extra dimensions model via 2 jets plus missing transverse momentum signatures at the LHC. We make predictions for both the signal and the dominant Zjj and Wjj backgrounds, where we introduce missing P_T-dependent jet selection cuts that ensure the smallness of the 2-jet rate over the 1-jet rate. With the same jet selection cuts, the distributions of the two jets and their correlation with the missing transverse momentum provide additional evidence for the production of an invisible massive object.
