Sigma meson mass and width at finite density
M.J. Vicente Vacas🇪🇸 · E. Oset🇪🇸
Abstract
The sigma meson mass and width are studied at finite baryonic density in the framework of a chiral unitary approach which successfully reproduces the meson meson phase shifts and generates the f0 and sigma resonances in vacuum.
