Octet baryon electromagnetic form factor double ratios in a nuclear medium
G. Ramalho, J. P. B. C. de Melo, K. Tsushima
The ratios of the baryon electric () to magnetic () form factors, , can provide us with important information on the structure of baryons in vacuum as demonstrat…
Rho-meson properties in medium
J. P. B. C. de Melo, K. Tsushima
Properties of -meson in symmetric nuclear matter are investigated in a light-front constituent quark model (LFCQM), using the in-medium inputs calculated by the quark-meson coup…
Spin-1 Particles with Light-Front Approach
J. P. B. C. de Melo, Anacé N. da Silva, Clayton S. Mello +1
For the vector sector, i.e, mesons with spin-1, the electromagnetic form factors and anothers observables are calculated with the light-front approach. However, the light-front qua…
Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
L. A. M. Salcedo, J. P. B. C. de Melo, D. Hadjmichef +1
We study the scaling of the meson mass splitting and the pseudoscalar weak decay constants with the mass of the meson, as seen in the available experimental data. We…
