摘要：
The soliton breathing mode is investigated in the framework of linear response theory within a Skyrme model vector meson stabilized. The effective Lagrangian considered includes the rho (introduced following the standard prescription of nonlinear chiral symmetry) and the omega mesons. The monopole response function is found to have a pronounced peak which is identified to the P11 (Roper) resonance. The results are compared to those obtained within the local approximation.
