Low Lying Scalar Resonances and Chiral Symmetry
Abstract
Current theoretical studies on the σ and κ resonances are reviewed. It is emphasized that all evidences accumulated so far are consistent with the picture that the σ meson is the chiral partner of the Nambu-Goldstone bosons in a linear realization of chiral symmetry.
