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…
Imaging the charge distributions of flavor-symmetric and -asymmetric mesons
Yin-Zhen Xu, Adnan Bashir, Khépani Raya +2
We investigate the internal structure of a comprehensive set of pseudoscalar and vector mesons, including both flavor-symmetric and flavor-asymmetric systems, by reconstructing the…
Insights into the transition
L. Albino, G. Paredes-Torres, K. Raya +2
We report novel theoretical results for the transition, utilizing a symmetry-preserving treatment of a vector$\,\otimes\,…
Heavy-light Pseudoscalar Mesons: Light-Front Wave Functions and Generalized Parton Distributions
B. Almeida-Zamora, J. J. Cobos-Martínez, A. Bashir +3
The internal structure of the lowest-lying pseudo-scalar mesons with heavy-light quark content is thoroughly studied using an algebraic model that has been successfully applied to…
Charge distributions of pseudo-scalar and vector mesons from Dyson-Schwinger equations
Y. -Z. Xu, K. Raya, J. Segovia +1
We combine the Dyson-Schwinger/Bethe-Salpeter equations framework with modern numerical reconstruction methods to derive the three-dimensional and transverse two-dimensional charge…
An algebraic model to study the internal structure of pseudo-scalar mesons with heavy-light quark content
B. Almeida-Zamora, J. J. Cobos-Martínez, A. Bashir +3
The internal structure of all lowest-lying pseudo-scalar mesons with heavy-light quark content is studied in detail using an algebraic model that has been applied recently, and suc…
