Numerical evaluation of non-infrared two-loop vertices
Abstract
Description
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 $\sin^2θ_{\rm eff}^{\rm lept}$ through the described techniques.
