Single Lepton Production at Large Transverse Momentum
We study the production of single isolated leptons at large transverse momentum, plT > MW /2. The dominant source of such leptons is production of an on-shell W boson recoiling against a hard jet. Vetoing this jet forces the W boson to be produced off resonance and significantly reduces the standard model cross section, thereby enhancing the discovery prospects for non standard model physics. A...
متن کاملMulti-lepton production at high transverse momentum at HERA
A search for events containing two or more high-transverse-momentum isolated leptons has been performed in ep collisions with the ZEUS detector at HERA using the full collected data sample, corresponding to an integrated luminosity of 480 pb. The number of observed events has been compared with the prediction from the Standard Model, searching for possible deviations, especially for multilepton...
متن کاملPrecision electroweak calculation of the production of a high transverse-momentum lepton pair at hadron colliders
We present a detailed study of the production of a high transverse-momentum lepton pair at hadron colliders, which includes the exact O(α) electroweak corrections properly matched with leading logarithmic effects due to multiple photon emission, as required by the experiments at the Fermilab Tevatron and the CERN LHC. Numerical results for the relevant observables of single Z-boson production a...
متن کاملW Boson Production at Large Transverse Momentum
The production of W bosons at large transverse momentum in pp̄ collisions is studied. The next-to-leading order cross section in this region is dominated by threshold soft-gluon corrections. The transverse momentum distribution of the W at the Tevatron is modestly enhanced when next-to-next-to-leading-order soft-gluon corrections are added, and the dependence on the factorization and renormaliza...
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...
