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,…
Medium effects on the electromagnetic form factors of the meson
Parada T. P. Hutauruk, Terry Mart, Kazuo Tsushima
The dynamics of partons inside the light meson is found to be essential for its properties and internal structure, both in free space and in the nuclear medium. In this paper,…
Electroweak form factors of baryons in dense nuclear matter
G. Ramalho, K. Tsushima, Myung-Ki Cheoun
There is evidence that the properties of hadrons are modified in a nuclear medium. Information about the medium modifications of the internal structure of hadrons is fundamental fo…
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…
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…
