Relation between bottom-quark MS Yukawa coupling and pole mass

We calculate the O(alphaalphas) corrections to the relationships between the (MS) over 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) over 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. (C) 2004 Elsevier B.V. All rights reserved.
