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…

Isospin breaking corrections in $2 I ¨ $ production in tau decays and $e^{+} e^{-}$ annihilation: consequences for the muon $g - 2$ and CVC tests

Gabriel LÃ³pez Castro, Alejandro Miranda, Pablo Roig

We revisit the isospin-breaking corrections relating the $e^{+} e^{-}$ hadronic cross-section and the tau decay spectral function, focusing on the di-pion channel, that gives the domina…

CP violation studies at Super Tau-Charm Facility

Hai-Yang Cheng, Zhi-Hui Guo, Xiao-Gang He +16

Charge-parity ( $C P$ ) violation in the tau-charm energy region is a promising area for sensitive tests of Standard Model (SM) predictions and searches for new, beyond the SM physi…

CP violation in two-meson Tau decays induced by heavy new physics

Daniel A. LÃ³pez Aguilar, Javier RendÃ³n, Pablo Roig

We apply the effective field theory formalism that was used to study CP violation induced by heavy new physics in the $I ¨ \to K_{S} I ¨ I^½_{I ¨} $ decays to the other two-meson tau decay ch…
