Baryons as Solitons in Chiral Quark Models
B. Golli, W. Broniowski, G. Ripka
We describe the formation of solitons in NJL-type models and discuss the influence of the regularization scheme on the stability of the solution. We concentrate on models with non-…
N-Delta axial transition form factors
B. Golli, L. Amoreira, M. Fiolhais +1
We review some basic properties of the N-Delta transition axial amplitudes and relate them to the strong pi-N-Delta form-factor. In models with the pion cloud we derive a set of co…
Axial currents in electro-weak pion production at threshold and in the Delta-region
S. Sirca, L. Amoreira, M. Fiolhais +1
We discuss electro-magnetic and weak production of pions on nucleons and show how results of experiments and their interpretation in terms of chiral quark models with explicit meso…
Axial Excitation of the Delta in Chiral Quark Models
S. Sirca, L. Amoreira, M. Fiolhais +1
We discuss electro-magnetic and weak axial N-Delta transition amplitudes in the linear sigma-model and the Cloudy-Bag Model as typical representatives of chiral quark models. We sh…
Excitation of non-quark degrees of freedom in N*
B. Golli, P. Alberto, M. Fiolhais
We study the contribution of glueball and sigma-meson degrees of freedom to nucleon excited states in the framework of a chiral version of the chromodielectric model. We have found…
Soliton Formation in Chiral Quark Models
Bojan Golli
We describe how the non-local regularization can be implemented in the calculation of solitons in the Nambu Jona-Lasinio model as well as in the equivalent linear sigma-model. We i…
