Numerical evaluation of non-infrared two-loop vertices

High Energy Physics - Phenomenology 2007-05-23 v1

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 sin2θefflept\sin^2\theta_{\rm eff}^{\rm lept} through the described techniques.
