Probing direct $CP$ violation in ${\Lambda }_b^0\to P_c^{+}{h}^{-}$ $(h=\pi ,K)$ with final-state rescattering

Zhu-Ding Duan, Tian-Liang Feng, Rui-Hui Li +4

The LHCb Collaboration recently reported a measurement of the difference in direct CP asymmetries for the decays ${\Lambda }_b^0\to J/\psi p{h}^{-}$ (with $h=K,\pi$), offering new experime…
