Description
In this talk, I will present recent results on precision calculations for the squark-(anti)squark production processes at the LHC with a center-of-mass energy of $\sqrt{S} = 13.6$ TeV in the framework of the Minimal R-symmetric Supersymmetric Standard Model (MRSSM). In contrast to the Minimal Supersymmetric Standard Model (MSSM), the MRSSM has a higher degree of symmetry, which affects, in particular, the production mechanisms. The known next-to-leading order (NLO) results are improved by threshold resummation, carried out using the direct QCD method, and reach next-to-next-to-leading logarithmic (NNLL) accuracy. New calculations required for the one-loop matching coefficients in the relevant production channels will be reported. The results show a significant suppression of the cross sections compared to the MSSM, effectively allowing lighter squark masses to be compatible with current LHC searches.
