Space- and time-like electromagnetic form factors of the baryon
L. Albino, B. Almeida-Zamora, A. Bashir +3
We present predictions for the elastic electromagnetic form factors of the baryon in both space-like and time-like regions, computed within a confining, symmetry-preserving fr…
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…
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…
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 $η…
$\mathbf{γ^{(*)} + N(940)\frac{1}{2}^+ \to N(1520)\frac{3}{2}^{-}}$ helicity amplitudes and transition form factors
L. Albino, G. Paredes-Torres, K. Raya +2
We recently reported new results on the $γ^{(*)} + N(940)\frac{1}{2}^+ \to Î(1700)\frac{3}{2}^{-}$ transition form factors using a symmetry-preserving treatment of a vector$\,\ot…
Insights into the $\mathbf{γ^{(*)} + N(940)\frac{1}{2}^+ \to Î(1700)\frac{3}{2}^{-}}$ transition
L. Albino, G. Paredes-Torres, K. Raya +2
We report novel theoretical results for the $γ^{(*)} + N(940)\frac{1}{2}^+ \to Î(1700)\frac{3}{2}^{-}$ transition, utilizing a symmetry-preserving treatment of a vector$\,\otimes…
