Soft gluon resummation for associated gluino-gaugino production at the LHC

We perform a threshold resummation calculation for the associated production of gluinos and gauginos at the LHC to the next-to-leading logarithmic accuracy. Analytical results are presented for the process-dependent soft anomalous dimension and the hard function. The resummed results are matched to a full next-to-leading order calculation, for which we have generalised the previously known results to the case of supersymmetric scenarios featuring non-universal squark masses. Numerically, the next-to-leading logarithmic contributions increase the total next-to-leading order cross section by 6% (20%) for central scale choices and gluino masses of 3 TeV (6 TeV) and reduce its scale dependence there from +/- 8% to below +/- 2%.
