Meson loops in the Nambu-Jona-Lasinio model
E. Nikolov, W. Broniowski, C. V. Christov +2
The effects of meson loops in the vacuum sector of the Nambu--Jona-Lasinio model are calculated. Using the effective action formalism we take consistently all next-to-leading-order…

Analytic structure of meson propagators in the proper-time regularized Nambu--Jona-Lasinio model
W. Broniowski, G. Ripka, E. Nikolov +1
We analyze the analytic structure of meson propagators in the Nambu--Jona-Lasinio model with a proper-time regulator. We show that the regulator produces unphysical complex singula…

Electric Polarizability of the Nucleon in the Nambu--Jona-Lasinio Model
E. Nikolov, W. Broniowski, K. Goeke
The electric polarizability of the nucleon is calculated in the soliton approach to the Nambu--Jona-Lasinio model. We analyze the leading- contributions, as well as the effect…
