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

摘要

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