Graviton production through photon-quark scattering at the LHC

TL;DR

This paper explores the production of gravitons via photon-quark interactions at the LHC within ADD and RS models, deriving constraints on model parameters through various decay channels and extra dimensional scenarios.

Contribution

It provides the first detailed analysis of real graviton emission via photon-quark scattering at the LHC in ADD and RS models, including multiple extra dimension scenarios and decay channels.

Findings

Constraints on ADD and RS model parameters were established.

Multiple extra dimensional scenarios (3-6) were considered in the analysis.

Decay channels G -> gamma gamma, e+ e-, mu+ mu- were used to set bounds.

Abstract

We have investigated real graviton emission in the ADD and RS model of extra dimensions through the photoproduction process pp-> p gamma p-> pGqX at the LHC. We have considered all contributions from the subprocesses gamma q -> G q, where q=u,d,c,s,b,anti-u,anti-d, anti-c, anti-s, anti-b quark. The constraints on model parameters of the ADD and RS model of extra dimensions have been calculated. During numerical calculations we have taken account of 3, 4, 5 and 6 large extra dimensional scenarios. The constraints on RS model parameters have been calculated by considering G -> gamma gamma, e^- e^+, mu^- mu^+ decay channels of the graviton.
