The effective electroweak mixing angle $sin^{2} θ_{e f f}$ with two-loop bosonic contributions

arXiv:hep-ph/0610312 · doi:10.1016/j.nuclphysb.2006.12.001

Abstract

We present the results for the full electroweak two-loop bosonic contributions to the effective leptonic mixing angle of the $Z$ boson, $sin^{2} θ_{eff}$ , 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.
