Graviton plus vector boson production to NLO in QCD at the LHC. (English) Zbl 1208.81206

Summary: We present the next-to-leading order QCD corrections to the associated production of the vector gauge boson \((Z/W^{\pm })\) and the graviton in the large extra dimension model at the LHC. We estimate the impact of the QCD corrections on the total cross sections as well as the differential distributions of the gauge bosons and find that they are significant. We also study the dependence of the cross sections on the arbitrary factorization scale and show the reduction in the scale uncertainties at NLO level. Further, we discuss the ultraviolet sensitivity of the theoretical predictions.
