Impact of eight-quark interactions in chiral phase transitions I: Secondary magnetic catalysis
A. A. Osipov, B. Hiller, A. H. Blin +1
The influence of a constant magnetic field on the order parameter of the four-dimensional Nambu and Jona-Lasinio model extended by the 't Hooft six-quark term and eight-quark inter…
Dynamical chiral symmetry breaking by a magnetic field and multi-quark interactions
A. A. Osipov, B. Hiller, A. H. Blin +1
Catalysis of dynamical symmetry breaking by a constant magnetic field in (3+1) dimensions is considered. We use the three flavour Nambu -- Jona-Lasinio type model with 't Hooft and…
Lowering the critical temperature with eight-quark interactions
A. A. Osipov, B. Hiller, J. Moreira +2
It is shown that eight-quark interactions, which are needed to stabilize the ground state of the combined three flavor Nambu -- Jona-Lasinio and 't Hooft Lagrangians, play also an…
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…
Multi-quark interactions with a globally stable vacuum
Alexander A. Osipov, Brigitte Hiller, Joao da Providencia
It is shown that eight-quark interactions stabilize the asymmetric ground state of the well-known model with four-quark Nambu -- Jona-Lasinio and six-quark 't…
