Description
Motivated by the recent 3.9$\sigma$ evidence for CP violation from the LHCb collaboration in decays of an anti-triplet beauty baryon to a charmonium, an octet baryon, and a pseudoscalar meson,
we perform, for the first time, a systematic analysis of this class of decays within the framework of flavor $SU(3)$ symmetry.
Several predictions for branching ratios and CP violating relations which can be tested in future experiments are found, in particular $\Delta A_{CP} = A_{CP}(\Lambda_b^0 \to p \pi^- J/\psi) - A_{CP}(\Lambda_b^0 \to p K^- J/\psi) = A_{CP}(\Lambda_b^0 \to n \pi^0 J/\psi) - A_{CP}(\Lambda_b^0 \to (n K_S, n K_L) J/\psi)$. Our results provide guidance to test the availability of $SU(3)$ symmetry and search for possible CP violation effects in this class of decays.
