EFFECT OF VECTOR-MESONS ON THE PHYSICAL-PROPERTIES IN THE NAMBU-JONA-LASINIO MODEL

The effects of vector meson on the static properties of the nucleon ar e investigated using the collective quantization in the Nambu-Jona-Las inio model. The soliton solution including rho and omega is found by d igonalizing the non-hermitian Euclidean Dirac operator. The vector mes on components excited during the collective rotation are solved approx imately using the gradient expansion. We evaluate the moment of inerti a and the magnectic moment. Various effects and problems of the vector mesons are discussed.
