Two-loop matching coefficients for the top-quark mass at O(αs2) in the MSSM — •David Kunz and Luminita Mihaila — KIT, Karlsruhe, Germany
The top quark, as the heaviest elementary particle currently known, is expected to play a central role in elucidating the physics that lies beyond the Standard Model. Especially, the prediction of the running top quark mass at high energy scales, where the new physics become active, is required for precision tests of the various models.
In this talk, we report on the computation of the two-loop matching coefficients of the top quark mass in the framework of the Minimal Supersymmetric SM, taking into account only the dominant corrections proportional to the strong coupling constant αs. Numerical effects for certain supersymmetric scenarios will be also presented.
