Tensor Excitations in Nambu - Jona-Lasinio Model
arXiv:hep-ph/9610220
Abstract
It is shown that in the one-flavour NJL model the vector and axial-vector quasiparticles described by the antisymmetric tensor field are generated. These excitations have tensor interactions with quarks in contrast to usual vector ones. Phenomenological applications are discussed.
