论文摘要
可以根据最终状态的极化来构建大量可观察物，同时考虑中性中性介子$（p^0 \ text {or} \ bar p^0）$的衰减到两个向量粒子。但是，所有这些可观察到的物体并非彼此独立，因为只有少数独立的理论参数来控制整个动力学，因此可以观察到的各种关系。在本文中，我们研究了在混合中违反T和CPT违规的情况下，可观察到的中性介子腐烂的中性膜腐烂的行为，并伴随着直接和间接的CP违规行为。我们仅以可观察的方式表达了这种情况的所有14个未知理论参数，并在观察到的观察结果中构建了三十四个关系的完整集，这些可观察到的违规将表示某些涉及直接违反CPT的新物理学的存在。此外，使用这种形式主义，我们也研究了三种特殊情况：a）SM场景，b）SM Plus Direct CP违规c）SM SM Plus T和CPT违反混合物。
A large number of observables can be constructed from differential decay rate based on the polarization of final state while considering decay of a neutral meson $(P^0 \text{ or } \bar P^0)$ to two vector particles. But all of these observables are not independent to each other since there are only a few independent theoretical parameters controlling the whole dynamics and therefore various relations among observables emerge. In this paper, we have studied the behaviour of observables for neutral meson decaying to two vectors in presence of T and CPT violations in mixing accompanied by both direct and indirect CP violations. We have expressed all of the fourteen unknown theoretical parameters for this scenario in terms observables only and constructed the complete set of thirty four relations among observables whose violation would signify the existence of some new Physics involving direct violation of CPT. In addition, using this formalism we have studied three special cases too: a) SM scenario, b) SM plus direct CP violation c) SM plus T and CPT violation in mixing.
