Constraints on Randall-Sundrum model from the events of dijet production with QCD next-to-leading order accuracy at the LHC

TL;DR

This paper investigates dijet production at the LHC within the Randall-Sundrum model, demonstrating significant NLO QCD corrections that enhance cross sections and constrain model parameters based on experimental data.

Contribution

It provides the first detailed NLO QCD analysis of dijet production in the Randall-Sundrum model, including cross section enhancements and parameter space constraints.

Findings

NLO QCD corrections increase cross sections by over 80%.

Reduced scale dependence at NLO improves prediction stability.

Experimental data constrains KK graviton mass and coupling parameters.

Abstract

We study the dijet production in Randall-Sundrum model at the LHC with QCD next-to-leading(NLO) order accuracy. Our results show that the QCD NLO corrections can increase the total cross sections by more than $80\%$ and reduce the scale dependence. We also explore in detail several important kinematic distributions at the NLO level. Moreover, we discuss the upper limits of the KK graviton excluded mass range and the allowed parameter space for the coupling constant and KK graviton mass, using the experiment data.
