Leading-twist proton parton distribution amplitude from scalar and axial-vector diquark correlations

B. Almeida-Zamora, L. Albino, C. Mezrag +1

We compute the leading-twist proton parton distribution amplitude (PDA) using algebraic representations of the nucleon Faddeev wave function inspired by perturbation-theory integra…

Electromagnetic form factors of the baryon: space-like structure and time-like extrapolation

L. Albino, B. Almeida-Zamora, A. Bashir +3

We calculate the elastic electromagnetic multipole form factors of the baryon using a symmetry-preserving vectorvector contact interaction in rainbow--ladder tru…

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

Anam Ashraf, Faisal Akram, M. Jamil Aslam +3

We present a comprehensive analysis of the Landau-Khalatnikov-Fradkin transformations for the charged fermion propagator in reduced quantum electrodynamics (RQED). Starting from th…

A multidimensional landscape of the and mesons

L. Albino, K. Raya, R. J. Hernández-Pinto +4

We employ a recently proposed form-invariant algebraic model for the quark propagator and the Bethe-Salpeter amplitude of pseudoscalar mesons to study the internal structure of …

Unified Description of Pseudoscalar Meson Structure from Light to Heavy Quarks

B. Almeida-Zamora, L. Albino, A. Bashir +2

We present a comprehensive review of the structure of pseudoscalar mesons within an algebraic model formulated in the light-front framework. The approach provides a unified descrip…
