Slepton pair production with POWHEG — Barbara Jäger, Andreas von Manteuffel, and •Stephan Thier — Johannes Gutenberg University, 55099 Mainz, Germany

We present an analysis of supersymmetric QCD effects on the pair production of scalar lepton superpartners at the LHC. Our approach is based on the POWHEG method for the matching of next-to-leading order calculations to parton showers and builds upon the publicly available POWHEG BOX framework.

Taking account of recent experimental bounds on the masses of supersymmetric particles, we identify dominant contributions in the perturbative corrections. Fixed-order calculations and parton showers provide accurate descriptions of jets in complementary kinematic regions. We compare both methods in detail under realistic selection cuts.
