NNLL-fast 2.0: Coloured Sparticle Production at the LHC Run 3 with √(S) = 13.6 TeV
arxiv(2024)
摘要
We report on updated precision predictions for total cross sections of
coloured supersymmetric particle production at the LHC with a centre-of-mass
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 soft-gluon 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-of-the-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.
