Abstract

In this paper we compute the O(αsαt)\mathcal{O}(\alpha_s \alpha_t) threshold corrections to the running strong coupling constant, the top-Yukawa coupling and the top-quark mass within the MSSM. These parameters present a non-decoupling behaviour with the supersymmetry scale MSUSYM_{\rm SUSY}. Our numerical analysis shows that the mixed QCD-Yukawa corrections can amount to few GeV for the running top-quark mass and range at the percent level for the top-Yukawa coupling.
