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…
Octet baryon electroweak form factors in dense nuclear matter
G. Ramalho, K. Tsushima, Myung-Ki Cheoun
Motivated by the necessity of developing theoretical models for studying the electroweak structure of baryons in a nuclear medium, we apply a covariant quark model to study interac…
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,…
Microscopic study of nuclei synthesis in pycnonuclear reaction C + C in neutron stars
S. P. Maydanyuk, Ju-Jun Xie, V. S. Vasilevsky +1
Purpose To investigate synthesis of nuclei in pycnonuclear reactions in dense medium of neutron stars on the basis of understanding, how the compound nucleus is formed during colli…
Manifestation of quark effects in nuclei via bremsstrahlung analysis in the proton-nucleus scattering
Sergei P. Maydanyuk, K. Tsushima, G. Ramalho +1
\textbf{Background} (1) The incoherent emission of photons is dominant comparing to coherent one in proton-nucleus scattering. The incoherent bremsstrahlung is very sensitive to th…
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…
