“…The fit results for Λ 0 b → pK − π + π − , Λ 0 b → pK − K + K − , and Ξ 0 b → pK − K − π + decays are shown in figures 1, 2, and 3, respectively. The signal yields, 19877 ± 195, 5297 ± 83, and 709 ± 45, respectively, are compatible with the previously measured branching fractions [33], once the selection efficiencies are taken into account. In the Λ 0 b → pK − π + π − and the Λ 0 b → pK − K + K − decay modes, signals consistent with the χ c0 (1P ) charmonium resonance are observed in the π + π − and the K + K − fast invariant-mass distributions, which are shown in figure 6 in appendix A.…”

A search for CP and P violation using triple-product asymmetries is performed with Λ 0 b → pK − π + π − , Λ 0 b → pK − K + K − and Ξ 0 b → pK − K − π + decays. The data sample corresponds to integrated luminosities of 1.0 fb −1 and 2.0 fb −1 , recorded with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV, respectively. The CP-and Pviolating asymmetries are measured both integrating over all phase space and in specific phase-space regions. No significant deviation from CP or P symmetry is found. The first observation of Λ 0 b → pK − χ c0 (1P)(→ π + π − , K + K −) decay is also reported.

“…Starting with the symmetries of the effective Hamiltonian, we relate or neglect reduced SU (3) amplitudes to derive several sum rules relations between amplitudes and relations between CP asymmetries while indicating more general relations that continue to hold when the SU (3) symmetry is no longer exact. This study is crucial for a detailed analysis of the CP asymmetry measurements in bottom baryons decays at the CDF and LHCb in recent times [76][77][78][79][80][81][82][83].…”

Nonleptonic beauty baryon decays and CP asymmetries based on an SU(3) -flavor analysis

We consider hadronic weak decays of beauty-baryons into charmless baryons and pseudoscalar mesons in a general framework based on SU (3) decomposition of the decay amplitudes. The advantage of the approach lies in the ability to perform an SU (3) analysis of these decays without any particular set of dynamical assumptions while accounting for the effects of an arbitrarily broken SU (3) flavor symmetry. Dictated by the symmetries of the effective Hamiltonian that allow us to relate or neglect reduced SU (3) amplitudes, we derive several sum rule relations between amplitudes and relations between CP asymmetries in these decays and identify those that hold even if SU (3) is broken.
