arXiv:hep-ph/0602029 · doi:10.1016/j.nuclphysbps.2006.03.036
Abstract
Details of the recent calculation of the two-loop bosonic corrections to the effective leptonic weak mixing angle are presented. In particular, the expansion in the difference of the W and Z boson masses is studied and some of the master integrals needed are given in analytic form.
