Electroweak precision pseudo-observables at the $e^{+} e^{-}$ Z-resonance peak

arXiv:2012.06598

Abstract

Phenomenologically relevant electroweak precision pseudo-observables related to Z-boson physics are discussed in the context of the strong experimental demands of future $e^{+} e^{-}$ colliders. The recent completion of two-loop Z-boson results is summarized and a prospect for the 3-loop Standard Model calculation of the Z-boson decay pseudo-observable is given.
