Final-state rescattering mechanism in bottom-baryon decays

Zhu-Ding Duan, Jian-Peng Wang, Run-Hui Li +2

The first observation of $CP$ violation in baryon decays was recently reported by the LHCb collaboration in ${\Lambda }_b^0\to p{K}^{-}{\pi }^{+}{\pi }^{-}$ with $A_{CP}=(2.45\pm 0.46\pm 0.10)\%$, which…
