Threshold and transverse-momentum resummations for gaugino-pair hadroproduction
Abstract
We present precision calculations of the invariant-mass and transverse-momentum distributions of gaugino pairs produced at hadron colliders. We implement the threshold and transverse-momentum resummation formalisms at next-to-leading order accuracy and match the obtained result to the perturbative prediction at O(alphas). We compare the various resummed cross sections with the perturbative results and Monte Carlo predictions. The theoretical uncertainties coming from renormalisation and factorisation scale variations are also discussed.
