Abstract
We consider the
SU(2) Quasilocal Quark Model
of the NJL-type including vector
and axial-vector four-fermion interaction vertices with derivatives. The mass
spectrum and a set of model-independent relations for the ground and first-excited
states are calculated.
The chiral-symmetry restoration sum rules in these
channels are imposed for matching to QCD at intermediate energies
in order to get a number of constraints on parameters of the
SU(2) QQM.
