On isotropic invariance of CP-noninvariant electromagnetic vertices cp -非不变电磁顶点的各向同性不变性
Physics Letters
Pub Date : 1966-12-05 DOI: 10.1016/0031-9163(66)91015-8
L.B. Okun

The isotopic selection rules are discussed in the framework of a scheme of strong CP-violation proposed by Lee. (According to these scheme the charge conjugation operators Cst and Cγ leaving invariant strong and electromagnetic interactions, respectively, do not coincide with each other.) It is shown that in this scheme CP-noninvariant vertices describing the emission of photons by ordinary hadrons must be necessarily isotopically invariant (ΔI = 0) independent of whether the principle of minimal electromagnetic interaction is applicable to so called a-particles and whether these particles are isottopic singlets.

在Lee提出的强cp违背方案框架内讨论了同位素选择规则。(根据这些方案，电荷共轭算子Cst和Cγ分别留下不变的强相互作用和电磁相互作用，彼此不重合。)结果表明，在该方案中，描述普通强子发射光子的cp -非不变顶点必须是同位素不变的(ΔI = 0)，与最小电磁相互作用原理是否适用于所谓的a粒子以及这些粒子是否是同位素单重态无关。
