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…

Novel method for determining the light quark mass ratio using $η^{'} \to η π π$ 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…

Improved $π^{0}, η, η^{'}$ transition form factors in resonance chiral theory and their $a_{μ}^{HLbL}$ contribution

Emilio J. Estrada, Sergi Gonzàlez-Solís, 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…

On the $η_{1} (1855)$ , $π_{1} (1400)$ and $π_{1} (1600)$ as dynamically generated states and their SU(3) partners

Mao-Jun Yan, Jorgivan M. Dias, Adolfo Guevara +2

In this work, we interpret the newly observed $η_{1} (1855)$ resonance with exotic $J^{P C} = 1^{-+}$ quantum numbers in the $I = 0$ sector, reported by the BESIII Collaboration, as a dyna…

Tension between $e^{+} e^{-} \to η π^{-} π^{+}$ and $τ^{-} \to η π^{-} π^{0} ν_{τ}$ data and non-standard interactions

Saray Arteaga, Ling-Yun Dai, Adolfo Guevara +1

We show the discrepancy between the isospin-rotated $e^{+} e^{-} \to η π^{-} π^{+}$ cross-section -- measured by various collaborations -- and the Belle $τ^{-} \to η π^{-} π^{0} ν_{τ}$ spectrum, which canno…

The $τ \to ν_{τ} π e^{+} e^{-}$ decay revisited

Adolfo Guevara

The recent results from Belle of the $τ^{-} \to ν_{τ} π^{-} e^{+} e^{-}$ analysis has incentivated us to make a reanalysis of a former work where the Structure Dependent parts are obtained using…
