I discuss the weak scale threshold corrections in supersymmetric models. I describe the ``match and run" approximation to the threshold corrections and compare with the exact one-loop results. With explicit examples I show that in cases without large hierarchies in the mass spectra the ``match and run" approximation can lead to order $\cal{O}$(1) errors in the determination of the threshold corrections. I demonstrate how to obtain the threshold-corrected Yukawa coupling from the fermion pole…

Two-loop $\cal O$$(\alpha_{s}^2)$ MSSM corrections to the pole masses of heavy quarks
Abstract. We present the results for two-loop MSSM corrections to the relation between pole and running masses of heavy quarks up to the order $\cal O$$(\alpha_{s}^2)$. The running masses are defined
