TTP02-33 Two-loop O(alpha_s^2) MSSM corrections to the pole masses of heavy quarks.

We present 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 in \DR scheme, usually used in multiloop calculations in supersymmetric theories. An analysis of the value of these corrections in different regions of the parameter space is provided.
