A nonlinear chiral Lagrangian framework for scalar mesons below 2 GeV [the I =l/2 states: κ(900) and [Formula: see text]; the I=1 states: a0(980) and a0(1450); and the I=0 states: α(550), f0(980), f0(1370), f0(1500) and f0(1710)] is presented. This framework is formulated in terms of two meson nonets with a mixing mechanism dictated by SU (3) symmetry and its breakdown.
