Scientific paper

Methods of Borel integration to calculate the binding ground energies and
mass of b-barb quarkonia are presented. The methods take into account the
leading infrared renormalon structure of the "soft" binding energy E(s) and of
the quark pole masses mq, and the property that the contributions of these
singularities in M(s) = 2 mq + E(s) cancel.
