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…
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…
