N2 - We compute the top mass dependent NLO strong interaction matching conditions to the ΔF = 2 effective Hamiltonian in the general MSSM. We study the relevance of such corrections, comparing its size with that of previously known NLO corrections in the limit m t → 0, in scenarios with degeneracy, alignment, and hierarchical squarks. We find that, while these corrections are generally small, there are regions in the parameter space where the contributions to the Wilson coefficients C 1 and C 4 could partially overcome the expected suppression m t/M SUSY. © SISSA 2012.
