Effective Lagrangian with vector mesons : Linear response theory
Abdellatif Abada
Abstract
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 ρ (introduced following the standard prescription of nonlinear chiral symmetry) and the ω 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.
