“…Such a Lagrangian is chirally invariant and incorporates current-field identities [2] as well as Sakurai's universality [15]. For a particular set of parameters the KSFR relation [20][21] and the Weinberg sum rule [22] are reproduced.…”

Abstract.We study the effect of vector and axial isovector mesons in the soliton of the SU(2) NJL-model for static hedgehog configurations and on the chiral circle. The Lagrangian reproduces Sakurai's Universality and implements vector dominance through current-field identities. The parameters of the Lagrangian are fixed by means of a heat-kernel expansion up to second order taking the A-~ mixing into account. For the corresponding set of parameters we find solitons for constituent quark masses between M N265--345 MeV which are much lower than those found without vector mesons. For the value M= 315 MeV which corresponds both to the KSFR relation 2gpf~2 2 -mp-2 and the Weinberg sum rule m 2 = 2m 2 the soliton has a clearly negative quark eigenvalue. The soliton mass is about 1100 MeV. For this choise of parameters the radius and axial coupling constant turn out to be too small.

“…An extension of this model, already discussed in Refs. [2][3][4][5]9], is to add the dynamics of vector mesons and to incorporate the idea of universal coupling [21]. This can be achieved by considering the vector mesons as massive gauge fields, following also the scheme of Ref.…”

We present a model for describing nuclear matter at finite density based on quarks interacting with chiral fields, σ and π and with vector mesons introduced as massive gauge fields. The chiral Lagrangian includes a logarithmic potential, associated with the breaking of scale invariance. We provide results for the soliton in vacuum and at finite density, using the Wigner-Seitz approximation. We show that the model can reach higher densities respect to the linear-σ model and that the introduction of vector mesons allows to obtain saturation. This result was never obtained before in similar approaches.

The decay width of the meson is considered by using the hypothesis of a partially conserved axialvector current and the equal-time commutation relations of the chiral SU(3)®SU(3) current algebra. We obtain T( -> JOT) =3.9 MeV to be compared with the latest experimental value V**** (-+ KK) = 4.0±1.0 MeV. A comparison with the results of the SU(S) symmetry is made, and the electromagnetic decay modes of the are also discussed.
