论文摘要
有人建议通过在底部和迷人的哈子的四体衰减中通过两倍的角度分布来搜索$ c \！p $。两倍角度分布中的两个极角是相关的，与之中间共振的干扰是一个重要的起源。这些干扰将使曲目留在两倍的角度分布中，可以研究$ c \！p $违规。当所有中间共振都不同，这是四体衰减所独有的，请特别注意。建议通过分析两倍的角度分布来寻找四体衰减中的$ c \！本文提出的方法也广泛适用于其他四体衰减过程。
It is proposed to search for $C\!P$ violation through the two-fold angular distributions in the four-body decays of bottom and charmed hadrons. The two polar angles in the two-fold angular distributions are correlated, to which the interferences of intermediate resonances are one important origin. These interferences will leave tracks in the two-fold angular distributions, with which the $C\!P$ violation can be studied. Special attention is paid to the case when all the intermediate resonances are different, which is unique to four-body decays. It is suggested to look for $C\!P$ violation in four-body decays such as $Λ_b^0\to p π^-π^+π^-$ through the analysis of the two-fold angular distributions. The method proposed in this paper is also widely applicable to other four-body decays processes.
