Electromagnetic ratios of hyperons at large timelike
G. Ramalho, M. T. Peña, K. Tsushima +1
In recent years, it has become possible to measure not only the magnitude of the electric () and magnetic () form factors of spin baryons, but also to measu…
Meson cloud contributions to the Dalitz decays of decuplet to octet baryons
G. Ramalho, K. Tsushima
We study the role of the meson cloud on the electromagnetic transitions from decuplet () to octet () baryons in terms of the squared four-momentum transfer . In the qua…
Electromagnetic Transition Form Factors of Baryon Resonances
G. Ramalho, M. T. Peña
Recent experimental and theoretical advancements have led to significant progress in our understanding of the electromagnetic structure of nucleons (), nucleon excitations ($N^\…
Electromagnetic form factors of baryons in nuclear medium
G. Ramalho, K. Tsushima, J. P. B. C. de Melo
The electromagnetic structure of the baryons is modified in the nuclear medium. The modifications can be inferred from the comparison between the electromagnetic form factors in me…
Electromagnetic form factors of the baryon in the spacelike and timelike regions
G. Ramalho
We present complete calculations of the electromagnetic form factors of the in the spacelike region and in the timelike region. The four elastic form factors: electric charge…
Covariant model for the Dalitz decay of the resonance
G. Ramalho, M. T. Peña
We develop a covariant model for the transition in the timelike kinematical region, the region where the square momentum transfer is positive. Our star…
