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-…

Vacuum properties in the presence of quantum fluctuations of the quark condensate
G. Ripka
The quantum fluctuations of the quark condensate are calculated using a regulated Nambu Jona-Lasinio model. The corresponding quantum fluctuations of the chiral fields are compared…
