摘要

讨论了非轻子超子衰变中普遍V-A相互作用和全局对称性存在的可能性。实际衰变中出现的偏离预期对称性的现象，可以用超子的介子结构来解释。定义了一个新的等压自旋，等于所有重子的1/2，等于k介子的0或1。它与全局对称的思想密切相关，并且在非轻子衰变中守恒。

Global symmetry and the conservation of isobaric spin in non-leptonic hyperon decays

The possible existence of a universal V–A interaction and of global symmetry in non-leptonic hyperon decay is discussed. Deviations from the expected symmetry, which occur in actual decays, are explained in terms of the meson structure of the hyperons. A new isobaric spin is defined, equal to 1/2 for all baryons and to 0 or 1 for K-mesons. It is closely connected with the idea of global symmetry, and is conserved in non-leptonic decays.
