Abstract

We report on updated precision predictions for total cross sections of coloured supersymmetric particle production at the LHC with a centre-ofmass energy of √ S = 13.6 TeV, computed with the modern PDF4LHC21 set.The cross sections are calculated at an approximated NNLO accuracy in QCD and contain corrections from the threshold resummation of softgluon emission up to NNLL accuracy as well as Coulomb-gluon contributions including bound-state terms.The corrections are found to increase the cross sections and reduce the theoretical uncertainty as compared to the best available fixed-order calculations.These predictions constitute the state-ofthe-art calculations and update the existing results for √ S = 13 TeV.We make our new results publicly available in the version 2.0 update to the code package NNLL-fast.
