OZI violating eight-quark interactions as a thermometer for chiral transitions
A. A. Osipov, B. Hiller, J. Moreira +1
This work is a follow-up of our recent observation that in the SU(3) flavor limit with vanishing current quark masses the temperature for the chiral transition is substantially red…
Explicit chiral symmetry breaking and the 1/N expansion in models with multi-fermion interactions
Alexander A. Osipov, Brigitte Hiller, Alex H. Blin
Explicit chiral symmetry breaking is a natural feature of many QCD inspired models with multi-quark interactions. To carry out the 1/N expansion of these theories, one integrates o…
Analytic perturbation theory versus 1/N expansion in the Gross-Neveu model
Alexander A. Osipov, Brigitte Hiller, Alex H. Blin
The 1/N expansion can be successfully used to calculate the Green functions of the two-dimensional O(2N) Gross - Neveu model. In parallel, the methods of analytic perturbation theo…
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…
