Stable Multiquark Interactions

B. Hiller, A. A. Osipov, A. H. Blin +1

The necessity of adding higher order multiquark interactions to the three flavor NJL model with breaking, in order to stabilize its vacuum, is discussed.

Effects of eight-quark interactions on the hadronic vacuum and mass spectra of light mesons

Alexander A. Osipov, Brigitte Hiller, Alex H. Blin +1

The combined effective low energy QCD Lagrangians of Nambu -- Jona-Lasinio (NJL) and 't Hooft are supplemented with eight-quark interactions. This work is a follow-up of recent fin…

pi pi scattering in a nonlocal Nambu -- Jona-Lasinio model

A. A. Osipov, A. E. Radzhabov, M. K. Volkov

We consider a nonlocal version of the Nambu and Jona-Lasinio model. The nonlocality is contained in the quark-antiquark bilinears of the four-quark vertices as a form factor of the…

Functional Integral Approaches to the Bosonization of Effective Multi-Quark Interactions with $U_\A(1)$ Breaking

Brigitte Hiller, Alexander A. Osipov, Veronique Bernard +1

Low energy hadron phenomenology involving the (u,d,s) quarks is often approached through effective multi-quark Lagrangians with the symmetries of QCD. A very successful approach co…

Stationary phase corrections in the process of bosonization of multi-quark interactions

Alexander A. Osipov, Brigitte Hiller, Joao Moreira +1

The functional integration over the auxiliary bosonic variables of cubic order related with the effective action of the Nambu -- Jona-Lasinio model with 't Hooft term has recently…
