  The production of supersymmetric stop-antistop pairs at the Large Hadron
Collider (LHC) is studied including corrections from soft-gluon resummation up
to next-to-next-to-leading logarithmic (NNLL) accuracy in the Mellin-space
approach. Additionally, corrections to the hard-matching coefficient at
one-loop and Coulomb contributions at two-loop order are considered. The NNLL
corrections enhance the cross section for all stop masses at centre-of-mass
energies of 8 and 13 TeV compared to the previously calculated predictions at
next-to-leading logarithmic (NLL) accuracy. Furthermore, a slight increase in
the dependence on the additional stop-mixing parameters is observed.
