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


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… (More)
