High Energy Physics - Phenomenology 2008-11-26 v2

Abstract

We present the results for the full electroweak two-loop bosonic contributions to the effective leptonic mixing angle of the ZZ boson, sin2θeff\sin^2\theta_{\rm eff}, in the Standard Model. A method applied to extract collinear divergences from two-loop vertex-functions is described. Comparisons of our results with those from a recent previous calculation show complete agreement.
