In-Medium Pion Valence Distribution Amplitude
K. Tsushima, J. P. B. C de Melo
After a brief review of the quark-based model for nuclear matter, and some pion properties in medium presented in our previous works, we report new results for the pion valence wav…
Exciting flavored bound states
E. Rojas, B. El-Bennich, J. P. B. C. de Melo
We study ground and radial excitations of flavor singlet and flavored pseudoscalar mesons within the framework of the rainbow-ladder truncation using an infrared massive and finite…
The photon-pion transition form factor: incompatible data or incompatible models?
J. P. B. C. de Melo, B. El-Bennich, T. Frederico
The elastic and transition form factors of the pion along with its usual static observables are calculated within a light-front field approach to the constituent quark mod…
Towards flavored bound states beyond rainbows and ladders
B. El-Bennich, E. Rojas, M. A. Paracha +1
We give a snapshot of recent progress in solving the Dyson-Schwinger equation with a beyond rainbow-ladder ansatz for the dressed quark-gluon vertex which includes ghost contributi…
Pair term in the Electromagnetic Current within the Front-Form Dynamics: Spin-0 Case
J. P. B. C. de Melo, T. Frederico, E. Pace +1
The frame and scale dependence of the pair-term contribution to the electromagnetic form factor of a spin-zero composite system of two-fermions is studied within the Light Front. T…
Covariant and ligth-front approaches to the rho-meson eletromagnetic form factors
J. P. B. C de Melo, T. Frederico
The rho-meson eletromagnetic form factors are calculated, both in covariant and light-front framework with constituintes quarks. The effect of the breakdown rotational symmetry for…
