An Effective Chiral Meson Lagrangian at from the NJL Model
A. A. Bel'kov, A. V. Lanyov, A. Schaale +1
In this work we present a strong chiral meson Lagrangian up to and including in the momentum expansion. It is derived from the Nambu--Jona-Lasinio (NJL) model using the he…

Chiral Meson Lagrangians from the QCD Based NJL Model Modified by Nonlocal Effects
A. A. Bel'kov, A. V. Lanyov, A. Schaale +1
Starting from a QCD inspired bilocal quark interaction we obtain a local effective meson lagrangian. In contrast to previous local (NJL-like) approaches, we include nonlocal correc…
