AbstractThe Letter is devoted to the calculation of the two-loop O(αsy2) and O(y4) MSSM corrections to the relation between the pole mass of the b-quark and its running mass in the 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(αs2) contribution calculated earlier
