论文摘要
在这封信中，我们提出了一种新颖的方法，以同时测量由$ t $ -ODD相关性引起的互补$ cp $违规及其相应的$ t $ -even-even-forparts，其中$ t $代表时间反转。我们的分析表明，在满足特定条件时，$ t $ -ODD和 - 相关性分别导致余弦和正弦的强阶段依赖性，分别对相应的$ cp $违规行为。此外，我们在强子腐烂中确定了这些$ cp $违反的对成对，这完全取决于螺旋幅度方案中相同的强阶段。这种互补性有效地减少了对$ cp $违规的研究的强烈依赖，同时还减轻了由于异常较小的强阶段而受到抑制$ cp $违规的风险。此外，我们的提案有可能在实验中尚未观察到的巴里昂腐烂中违反$ CP $违规的潜力。
In this letter, we propose a novel approach to concurrently measure the complementary $CP$ violation observables induced by $T$-odd correlations and their corresponding $T$-even counterparts, where $T$ represents time reversal. Our analysis demonstrates that $T$-odd and -even correlations, when satisfying specific conditions, result in cosine and sine strong phase dependencies of the corresponding $CP$ violation, respectively. Additionally, we identify pairs of these $CP$ violation observables in hadron decays depend on precisely the same strong phases within the helicity amplitude scheme. This complementarity effectively reduces the strong phase reliance in the study of $CP$ violation, while also mitigating the risk of suppressed $CP$ violation due to exceptionally small strong phases. Furthermore, our proposal holds potential for uncovering $CP$ violation in baryon decays that have not yet been observed in experiments.
