Scientific paper

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(alpha_s). 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.
