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…
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…
Gravitational form factors and mechanical properties of the nucleon in a meson dominance approach
Wojciech Broniowski, Enrique Ruiz Arriola
We analyze the gravitational form factors and mechanical properties of the nucleon, focusing on both some general issues as well as on modeling with meson dominance. We show that t…
Transverse densities of the energy-momentum tensor and the gravitational form factors the pion
Wojciech Broniowski, Enrique Ruiz Arriola
We present general features of the transverse densities of the stress-energy-momentum tensor in the pion. We show positivity of the transverse density of (analogo…
Scalar and tensor meson dominance and gravitational form factors of the pion
Enrique Ruiz Arriola, Wojciech Broniowski
We analyze the recent MIT lattice data for the gravitational form factors (GFFs) of the pion which extend up to for ~MeV~\cite{Hackett:2023nkr}. We sh…
