Matching coefficients for the strong coupling constant and the bottom quark mass to Os2) in the MSSMAndreas Bauer, Luminita Mihaila, •Jens Salomon, and Matthias Steinhauser — Institut für Theoretische Teilchenphysik (TTP), 76128 Karlsruhe, Germany

We compute the exact two-loop matching coefficients for the strong coupling constant αs and the bottom quark mass mb within the Minimal Supersymmetric Standard Model (MSSM), taking into account Os2) contributions from Supersymmetric Quantum Chromodynamics. We find that the explicit mass pattern of the supersymmetric particles has a significant impact on the predictions of αs and mb at high energies. Further on, the three-loop corrections are comparable to or even exceed the uncertainty due to the current experimental accuracy. In case of the the running bottom quark mass, they can reach in the large tanβ regime up to 30% of the tree-level value.
