Threshold Effects in Slepton Pair Production at the LHC
We present a study of threshold resummation effects for slepton pair production at the Large Hadron Collider (LHC). After confirming the known NLO QCD corrections and generalizing the NLO SUSY-QCD corrections to the case of mixing squarks in the virtual loop contributions, we employ the Mellin N -space resummation formalism to compute logarithmically enhanced soft-gluon terms to all perturbativ...
متن کاملTransverse-Momentum Resummation for Slepton-Pair Production at the LHC
We perform a first precision calculation of the transverse-momentum (qT ) distribution of slepton pair and slepton-sneutrino associated production at the CERN Large Hadron Collider (LHC). We implement soft-gluon resummation at the next-to-leading logarithmic (NLL) level and consistently match the obtained result to the pure fixed-order perturbative result at leading order (LO) in the QCD coupli...
متن کاملResonant Slepton Production at the LHC
We consider the resonant production of charged sleptons at the LHC via R-parity violation (6Rp ) followed by gauge decays to a charged lepton and a neutralino which then decays via 6Rp. This gives a signature of two like-sign charged leptons. In the simulation we include the full hadronisation via Monte Carlo programs. We find a background, after cuts, of 5.1± 2.5 events for an integrated lumin...
متن کاملSlepton pair production at hadron colliders
In R-parity conserving supersymmetric (SUSY) models, sleptons are produced in pairs at hadron colliders. We show that measurements of the longitudinal single-spin asymmetry at possible polarization upgrades of existing colliders allow for a direct extraction of the slepton mixing angle. A calculation of the transverse-momentum (qT ) spectrum shows the importance of resummed contributions at nex...
متن کاملTop-quark pair production near threshold at LHC
The next-to-leading order analysis for the cross section for hadroproduction of top quark pairs close to threshold is presented. Within the framework of non-relativistic QCD a significant enhancement compared to fixed order perturbation theory is observed which originates from the characteristic remnant of the 1S peak below production threshold of top quark pairs. The analysis includes all colo...
