On multi-particle functions and pion-decay constant in Nambu--Jona-Lasinio model
V. E. Rochev
The system of second-order equations of mean-field expansion is considered for Nambu--Jona-Lasinio model with chiral symmetry of SU(2)-group. The system includes equations for four…

On Equations for the Multi-quark Bound States in Nambu--Jona-Lasinio Model
R. G. Jafarov, V. E. Rochev
In present report we review some preliminary results of investigation of higher orders of mean-field expansion for Nambu--Jona-Lasinio model. We discuss first results of investigat…
