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

Understand

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.
