A novel method for searching the ${\Xi }_c^{0/+}$-${\Xi }_c^{\prime 0/+}$ mixing effect in the angular distribution analysis of a four-body ${\Xi }_c^{0/+}$ decay

Zhi Peng Xing, Yu ji Shi

In this work, we raised a novel method for searching the ${\Xi }_c^{0+}$-${\Xi }_c^{0+\prime }$ mixing effect in an angular distribution analysis of the ${\Xi }_c\to {\Xi }^{(\prime )}(\Lambda \pi ){\ell }^{+}\nu$ decay,…
