We study the effect of soft gluon emission in the hadroproduction of gluino-gluino and squark-antisquark pairs at the next-to-leading logarithmic accuracy within the framework of the minimal supersymmetric model. We present the calculation of the one-loop soft anomalous dimension matrices controlling the color evolution of the underlying hard-scattering processes. The numerical results for resummed cross sections for proton-proton collisions at the Large Hadron Collider are discussed in detail.

NNLL resummation for squark-antisquark pair production at the LHC (2011, unknown): “For squarkantisquark production, in addition to soft-gluon resummation, the Coulomb corrections have been resummed both by using a Sommerfeld factor [31] and by employing the framework of effective field theories [29].”
Search for supersymmetry in proton-proton collisions at 13 TeV in final states with jets and missing transverse momentum (2019, methodology): “The production cross sections are determined with approximate NNLO plus next-to-next-to-leading logarithmic (NNLL) accuracy [73–84].”
Gaugino production in proton-proton collisions at a center-of-mass energy of 8 TeV (2012, background): “production cross sections and their theoretical uncertainties have been updated to nextto-leading order (NLO) and next-to-leading logarithmic (NLL) accuracy for pp collisions with a center-of-mass energy of 7TeV [7–12].”
