Query: Analytical evaluation of certain on-shell two-loop three-point diagrams   An analytical approach is applied to the calculation of some
dimensionally-regulated two-loop vertex diagrams with essential on-shell
singularities. Such diagrams are important for the evaluation of QED
corrections to the muon decay, QCD corrections to top quark decays t->W^{+}b,
t->H^{+}b, etc.
