Dynamical Breaking to Special or Regular Subgroups in Nambu--Jona-Lasinio Model
arXiv:1911.09834 · doi:10.1093/ptep/ptaa001
Abstract
It is recently shown that in 4D Nambu--Jona-Lasinio (NJL) type models, the symmetry breaking into its special subgroups is not special but much more common than that into the regular subgroups, where the fermions belong to complex representations of . We perform the same analysis for NJL model for various with fermions belonging to an irreducible spinor representation of . We find that the symmetry breaking into special or regular subgroups has some correlation with the type of fermion representations; i.e., complex, real, pseudo-real representations.
