Graviton monojet production at NLO in the large extra dimensions — Stefan Karg¹, Michael Krämer¹, •Qiang Li², and Dieter Zeppenfeld² — ¹Institut für Theoretische Physik E, RWTH Aachen — ²Institut für Theoretische Physik, Universität Karlsruhe

We compute the O(α_s) QCD corrections to Kaluza-Klein (KK) graviton monojet production in the large extra dimensions model at the LHC. We make predictions for both the signal and the dominant Zj and Wj background at next-to-leading order. We study the scale dependence and PDF uncertainty of the differential cross sections and present distributions where the QCD corrections strongly modify the leading order results.
