RS model with a small curvature and Drell-Yan process at the LHC

TL;DR

This paper calculates the dilepton production distribution at the LHC within a small-curvature Randall-Sundrum model, accounting for graviton widths, and establishes discovery limits on the 5D gravity scale independent of the curvature parameter.

Contribution

It introduces a calculation of dilepton distributions in a small-curvature RS model considering graviton widths and derives parameter-independent discovery limits for the 5D gravity scale.

Findings

Discovery limits on M_5 are 17.8 TeV and 21.6 TeV for different luminosities.

Limits are independent of the curvature parameter κ.

The model's predictions can guide experimental searches at the LHC.

Abstract

The $p_{\perp}$-distribution for a dilepton production at the LHC with high luminosity is calculated in the Randall-Sundrum scenario with a small curvature $\kappa$. The widths of massive gravitons are taken into account. The discovery limits on 5-dimensional gravity scale $M_5$ are obtained to be 17.8 TeV and 21.6 TeV for $\sqrt{s} = 14$ TeV and integrated luminosities 1000 fb$^{-1}$ and 3000 fb$^{-1}$, respectively. Contrary to the standard RS model, these limits do not depend on parameter $\kappa$.
