2 GeV 以下标量介子的非线性手性拉格朗日框架 [I =l/2 状态:κ(900) 和 ; I=1 状态:a0(980) 和 a0(1450);并且I=0状态:α(550)、f0(980)、f0(1370)、f0(1500)和f0(1710)]被呈现。该框架是根据两个介子非网制定的,其混合机制由 SU(3) 对称性及其破坏决定。
A nonlinear chiral Lagrangian framework for scalar mesons below 2 GeV [the I =l/2 states: κ(900) and ; 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.
