Four-fermion operators, $Z$ -boson exchange, and $τ$ lepton dipole moments

JoÃ«l Gogniat, Joël Gogniat, Martin Hoferichter +1

Asymmetry measurements in $e^{+} e^{-} \to τ^{+} τ^{-}$ constitute a promising avenue to obtain competitive constraints on the $τ$ dipole moments, the anomalous magnetic moment $a_{τ}$ and the e…

The anomalous magnetic moment of the muon in the Standard Model: an update

R. Aliberti, T. Aoyama, E. Balzani +232

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_{I^} ¼$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

Towards testing $(g - 2)_{I ¨} $ in $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-}$ : radiative corrections and projections for Belle II

JoÃ«l Gogniat, Martin Hoferichter, Yannick Ulrich

The arguably most promising avenue towards testing physics beyond the Standard Model in the anomalous magnetic moment of the $I ¨ $ proceeds via suitably constructed asymmetries in $…
