abstract
We study the effect of soft gluon emission in the hadroproduction of squark-antisquark and gluino-gluino pairs at the next-to-leading logarithmic (NLL) accuracy within the framework of the minimal supersymmetric model. The one-loop soft anomalous dimension matrices controlling the colour evolution of the underlying hard-scattering processes are calculated. We present the resummed total cross sections and show numerical results for proton-proton collisions at 14 TeV. The size of the NLL contribution to the cross section and the reduction of the scale dependence of the theoretical predictions due to including soft gluon effects are discussed.

Search for supersymmetry using Higgs boson to diphoton decays at $\sqrt{s} =$ 13 TeV
No supersymmetry signal was found in Higgs-to-diphoton events, and new 95% CL limits exclude sbottom masses below 530 GeV and chargino-neutralino masses below 235-290 GeV in simplified SUSY models.
