Transverse-momentum, threshold and joint resummations for slepton pair production at hadron colliders
Abstract
We present precision calculations of the transverse-momentum spectrum and the invariant-mass distribution for slepton pair production at hadron colliders. We implement the transverse-momentum, threshold and joint resummation formalisms at the next-to-leading logarithmic accuracy and consistently match the obtained result with the pure perturbative result at the first order in the strong coupling constant, i.e. at order alphas. We give numerical predictions for selectron and stau pair production, and compare the various resummed cross sections with the perturbative result.
