Radiative Decays of Hyperons in the Skyrme Model: E2/M1 Transitions
A. Abada, H. Weigel, H. Reinhardt
We study the radiative decays of baryons in the framework of the SU(3) collective approach to the Skyrme model. We present the predictions for the decay widths…
Strange Nucleons and Hyperons as Chiral Solitons in the NJL Model
R. Alkofer, H. Weigel, H. Reinhardt +1
In the chirally symmetric Nambu--Jona-Lasinio model baryons are described as chiral solitons of mesonic quark--antiquark bound states. Hyperons are investigated in two complementar…
Monopole Excitations of Baryons in the Nambu--Jona--Lasinio Soliton Model
A. Abada, R. Alkofer, H. Reinhardt +1
We investigate the monopole excitations of the soliton in the Nambu--Jona--Lasinio model. By studying the solutions to the corresponding Bethe--Salpeter equation in the background…
Isovector response function of hot nuclear matter with Skyrme interactions
F. L. Braghin, D. Vautherin, A. Abada
We investigate the role of the effective nucleon-nucleon interaction in the description of giant dipole resonances in hot nuclei. For this purpose we calculate the response functio…
On the strange vector form factors of the nucleon in the NJL soliton model
H. Weigel, A. Abada, R. Alkofer +1
Within the Nambu--Jona--Lasinio model strange degrees of freedom are incorporated into the soliton picture using the collective approach of Yabu and Ando. The form factors of the n…
The giant resonances in hot nuclei: linear response calculations
Abdellatif Abada, Fabio L. Braghin, Dominique Vautherin
We calculate the isovector response function of hot nuclear matter using various effective Skyrme interactions. For Skyrme forces with a small effective mass the strength distribut…
