Electric and magnetic timelike form factors of hyperons at large transfer momentum
G. Ramalho, M. T. Peña, K. Tsushima +1
There has been considerable progress in the study of the electromagnetic form factors of baryons in the timelike region, through electron-positron scattering reactions ($e^+ e^- \t…
Timelike electromagnetic form factors of hyperons at large
G. Ramalho, M. T. Peña, K. Tsushima +1
In the last few years there has been considerable progress in the study of the electromagnetic form factors of baryons in the timelike region, through electron-positron scattering,…
Weak interaction axial form factors of the octet baryons in nuclear medium
G. Ramalho, K. Tsushima, Myung-Ki Cheoun
We study the axial-vector and the induced pseudoscalar form factors associated with the weak transitions between the octet baryon members in nuclear medium, using a covariant const…
Octet baryon electromagnetic form factors in nuclear medium
G. Ramalho, K. Tsushima, A. W. Thomas
We study the octet baryon electromagnetic form factors in nuclear matter using the covariant spectator quark model extended to the nuclear matter regime. The parameters of the mode…
Valence quark contributions for the gamma N -> P11(1440) form factors
G. Ramalho, Kazuo Tsushima
Using a covariant spectator quark model we estimate valence quark contributions to the F1*(Q2) and F2*(Q2) transition form factors for the gamma N -> P11(1440) reaction. The Roper…
