摘要 The possible final states for the decay K^0→ π＋π-π^0 have isospinI = 0, 1, 2, and 3. TheI= 0 andI= 2states have CP = ＋1 and Ks can decay into them without violating CP symmetry, but they are expected to be strongly suppressed by centrifugal barrier effects. The I = 1 and I = 3 states, which have no centrifugal barrier, have CP = -1 so that the Ks decay to these requires CP violation. The possible final states for the decay K^0→ π＋π-π^0 have isospinI = 0, 1, 2, and 3. TheI= 0 andI= 2states have CP = ＋1 and Ks can decay into them without violating CP symmetry, but they are expected to be strongly suppressed by centrifugal barrier effects. The I = 1 and I = 3 states, which have no centrifugal barrier, have CP = -1 so that the Ks decay to these requires CP violation.
