THE MODEL OF NAMBU AND JONA-LASINIO (NJL) USING THE K-DEFORMED POINCARE ALGEBRA

Recently it has been suggested that a K-deformed Poincare algebra, whi ch preserves rotational and translational symmetries, can be applied t o the Dirac-Coulomb problem to give epsilon=1/kappa<1 fm [L.C. Biedenh am, B, Mueller and M. Tarlini, Phys. Lett. B 318 (1993) 613], This sug gests applications in nuclear-particle physics, We apply it to the NJL model to show that the natural cut-off epsilon(-1) gives reasonable v alues of the dynamical quark mass, f(pi) and the quark condensate.
