Novel method for determining the light quark mass ratio using $I^\cdot^{'} \to I^\cdot I ¨ I ¨ $ decays

Adolfo Guevara, Feng-Kun Guo, Hao-Jie Jing

We propose a novel approach for extracting symmetry breaking effects from symmetry conserving three-body decays. The method is based on mapping the Dalitz plot to a unit disk, and…

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…

Improved $I ¨ ^{0}, I^\cdot, I^\cdot^{'}$ transition form factors in resonance chiral theory and their $a_{I^} ¼^{HLbL}$ contribution

Emilio J. Estrada, Sergi GonzÃ lez-SolÃs, Adolfo Guevara +1

Working with Resonance Chiral Theory, within the two resonance multiplets saturation scheme, we satisfy leading (and some subleading) chiral and asymptotic QCD constraints and accu…
