摘要：

The solitonic sector of the SU(2) NJL model with sigma, pi, rho, A1 and omega mesons is investigated. The scalar and pseudo-scalar meson fields are not constrained to the chiral circle condition, i.e. sigma2(r) + pi2(r) not-equal f(pi)2. We show numerically that the repulsive omega meson prevents the recently discovered collapse of the hedgehog soliton. A comparison of the linear and the nonlinear NJL model leads to similar solitonic properties. although the deviations from the chiral circle condition are found not to be small.
