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…

Simple explanation of strong suppression of fermionic EFT operators and custodial symmetry breaking

Adolfo Guevara, Fernando Alvarado, Juan José Sanz Cillero

The present approach relies on the SM chiral symmetry breaking pattern $S U (2)_{L} \otimes S U (2)_{R} \to S U (2)_{L + R}$ , with the EW Goldstone bosons given in a non-linear realization and t…
