Elastic form factors of axial-vector mesons: A contact interaction exploration

Roger J. Hernández-Pinto, L. X. Gutiérrez-Guerrero, Marco A. Bedolla, Juan P. Uribe-Ramírez et autres

We employ a symmetry-preserving treatment of the contact interaction within the coupled formalism of Schwinger-Dyson and Bethe-Salpeter equations to calculate the elastic form factors of axial-vector mesons. In this study, we present the computation of the charge radii, magnetic moments, and quadrupole …

Unified Description of Pseudoscalar Meson Structure from Light to Heavy Quarks

Bilgai Almeida Zamora, L. Albino, Adnan Bashir, J. J. Cobos-Martínez et autres

We review the structure of pseudoscalar mesons within an algebraic model formulated in the light-front framework. The approach provides a unified description of leading-twist parton distribution amplitudes, light-front wave functions, generalized parton distributions, parton distribution functions, elastic electromagnetic form factors, charge radii, …

Landau-Khalatnikov-Fradkin Transformations in Reduced Quantum Electrodynamics: Perturbative and Nonperturbative Dynamics of the Fermion Propagator

Anam Ashraf, Faisal Akram, M. Jamil Aslam, Dania Rodríguez-Tzintzun et autres

We present a comprehensive analysis of the Landau-Khalatnikov-Fradkin transformations for the charged fermion propagator in reduced quantum electrodynamics (RQED). Starting from the propagator in a reference gauge, we perform a gauge transformation to obtain its analytical expression valid to all orders in …

Imaging the charge distributions of flavor-symmetric and -asymmetric mesons

Yin-Zhen Xu, Adnan Bashir, Khépani Raya, J. Rodrı́guez-Quintero et autres

We investigate the internal structure of a comprehensive set of pseudoscalar and vector mesons, including both flavor-symmetric and flavor-asymmetric systems, by reconstructing their charge distributions from electromagnetic form factors. To achieve this, we employ a Maximum Entropy Method optimized for charge distributions, …

Radially excited pion: electromagnetic form factor and the box contribution to the muon's g-2*

Ángel S. Miramontes, Khépani Raya, Adnan Bashir, Pablo Roig

Abstract We investigate the properties of the radially excited charged pion, with a specific focus on its electromagnetic form factor (EFF) and its box contribution to the hadronic light-by-light (HLbL) component of the muon's anomalous magnetic moment, . Utilizing a coupled non-perturbative …
