The axial-vector nucleon form factor in the meson dominance picture: the role triangle singularities from a dispersive view
Enrique Ruiz Arriola, Pablo Sanchez-Puertas
The nucleon axial form factor is analyzed in terms of a dispersion relation comprising chiral perturbation theory (ChPT) and perturbative QCD (pQCD) in the low- and high-momentum r…
Hadronic form factors in QCD and the incompleteness problem in the time-like region
Enrique Ruiz Arriola, Pablo Sanchez-Puertas, Wojciech Broniowski
Hadronic form factors fulfill dispersion relations and superconvergence sum rules for their spectral density as genuine imprints of QCD. We show several instances where these condi…
Pseudoscalar meson dominance, the pion-nucleon coupling constant and the Goldberger-Treiman discrepancy
Enrique Ruiz Arriola, Pablo Sanchez-Puertas
We analyze the matrix elements of the pseudoscalar density with pion-quantum numbers in the nucleon in terms of dispersion relations, PCAC and pQCD asympto…

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…
Pion transverse charge density from annihilation data and logarithmic dispersion relations
Enrique Ruiz Arriola, Pablo Sanchez-Puertas, Christian Weiss
The transverse charge density of the pion is extracted from a dispersive analysis of the exclusive annihilation data. A logarithmic dispersion relation…

Maximilian Zillinger, Bastian Kubis, Pablo Sánchez-Puertas
It has been pointed out recently that a certain set of dimension-6 scalar - and -violating light-quark-muon operators may be tested in and decays to various final s…
