Dimensional Reduction in Nambu – Jona – Lasinio Model in External Chromomagnetic Field

چکیده
The effective dimensional reduction of fermion-antifermion pairing dinam-ics in Nambu-Jona-Lasinio model in external chromomagnetic field is considered. It is shown that such a field causes the reduction of the space dimension by one unit in contrast to an ordinary magnetic field which reduces it by two units. The enhancement of the dynamical chiral symmetry breaking due to the reduction is discussed.

Chromomagnetic Catalysis of Color Superconductivity in a (2+1)-dimensional NJL Model
The influence of a constant uniform external chromomagnetic field H on the formation of color superconductivity has been investigated. The consideration was performed in the framework of a (2+1)-dimensional Nambu–Jona-Lasinio model with two different four-fermionic structures responsible for < q̄q > and diquark < qq > condensates. In particular, it was shown that there exists a critical value Hc...

The mass generation in the (3 + 1)–dimensional supersymmetric Nambu–Jona–Lasinio model in a constant magnetic field is studied. It is shown that the external magnetic field catalyzes chiral symmetry breaking. It was shown in [2, 3] and later confirmed in [4, 5] that a constant magnetic field is a strong catalyst of dynamical chiral symmetry breaking, leading to the generation of a fermion dynam...
متن کاملThe Gross-Neveu Model and the Supersymmetric and Non–Supersymmetric Nambu–Jona–Lasinio Model in a Magnetic Field
The infrared dynamics in the (3 + 1)–dimensional supersymmetric and non–supersymmetric Nambu–Jona–Lasinio model in a constant magnetic field is studied. While at strong coupling the dynamics in these two models is essentially different, it is shown that the models become equivalent at weak coupling. In particular, at weak coupling, as the strength of the magnetic field goes to infinity, both th...

This is an english translation of the article, published in Russian journal Pis’ma Zh. Eksp. Teor. Fiz. (JETP Letters) [1]. It is well known that Nambu – Jona Lasinio (NJL) model [2, 3] is perfect laboratory for the investigations of low energy region in QCD. The subject of special interest is the spontaneous breaking of chiral symmetry. In the framework of NJL model this phenomenon was studied...
متن کاملChiral symmetry breaking by a non - Abelian external field in ( 2 + 1 ) - dimensions
We investigate the effect of a constant external non-Abelian field on chiral symmetry breaking in a (2+1)-dimensional Nambu-Jona-Lasinio model and in 3D QCD by solving the gap equation and the Bethe-Salpeter equation, and also by RG analysis. In the (2+1)-dimensional NJL model chiral symmetry breaking occurs for any weak coupling constant but in 3D QCD catalysis of chiral symmetry breaking does...
