Two-loop O(alphas y2) and O(y4) MSSM corrections to the pole mass of the b-quark
A. Bednyakov, A. Sheplyakov
Abstract
The paper is devoted to the calculation of the two-loop O(alphas y2) and O(y4) MSSM corrections to the relation between the pole mass of the b-quark and its running mass in DR scheme. To evaluate the needed diagrams the large mass expansion procedure is used. The obtained contributions are negative in most of the regions of the parameter space and partly compensate the positive O(alphas2) contribution calculated earlier.
