Relation between bottom-quark MS-bar Yukawa coupling and pole mass

Abstract

We calculate the O(alpha alpha_s) corrections to the relationships between the MS-bar Yukawa couplings and the pole masses of the first five quark flavours in the standard model. We also present the corresponding relationships between the MS-bar and pole masses, which emerge as by-products of our main analysis. The occurring self-energies are evaluated using the method of asymptotic expansion.Comment: 20 pages, 5 figures, to appear in Nucl. Phys.
