摘要：
We study the dijet production in the 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 Klauza-Klein graviton excluded mass range and the allowed parameter space for the coupling constant and Klauza-Klein graviton mass, using the experiment data.
