The effective electroweak mixing angle 2θeff with two-loop bosonic contributions
W. Hollik, U. Meier, S. Uccirati
Abstract
We present the results for the full electroweak two-loop bosonic contributions to the effective leptonic mixing angle of the Z boson, 2θ 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.
