Numerical evaluation of non-infrared two-loop vertices

Abstract

Some methods for the numerical computation of two-loop non-infrared vertices are reviewed. A new method is also proposed and compared to the old ones. Finally, some preliminary results are presented, concerning the evaluation of the fermionic corrections to ${\sin }^2{\theta }_{\mathrm{eff}}^{\mathrm{lept}}$ through the described techniques.
