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, $a_{μ}$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…

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…

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

Gabriel López 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…
