Abstract:
The partial-decay-rate asymmetries indicating the CP-violating effects in [Formula: see text] decays into two-body baryons are examined within the Kobayashi-Maskawa model. The branching ratios of the decays and the numbers of [Formula: see text] pairs needed for testing these effects are estimated. It turns out that the CP violation asymmetries and the branching ratios are generally small and it is difficult to test the effects in experiments.

Abstract:
The nonleptonic decays from [Formula: see text] and [Formula: see text] to an orbitally excited P-wave charmed meson are studied within the naive factorization hypothesis. Based on the Mandelstam formalism, and under the framework of the improved Bethe–Salpeter method, the hadronic matrix elements of the decays [Formula: see text] and [Formula: see text] are calculated, in which nonperturbative QCD effects are well considered by overlapping integral over the relativistic Salpeter wave functions of initial and final states. Some of these decays have sizable branching fractions and are expected

Abstract:
In this work, we investigate the resonant contributions of K 0 ∗ 1430 and K 0 ∗ 1950 in the three-body B s ⟶ D s K π within the perturbative QCD approach. The form factor F k π s is adopted to describe the nonperturbative dynamics of the S-wave K π system. The branching ratios of all concerned decays are calculated and predicted to be in the order of 1 0 − 10 to 1 0 − 5 . The ratio R of branching fractions between B 0 ⟶ D ¯ 0 K 0 ∗ 0 1430 ⟶ D ¯ 0 K + π − and B s 0 ⟶ D ¯ 0 K ¯ 0 ∗ 0 1430 ⟶ D ¯ 0 K − π + is predicted to be 0.0552, which implies the discrepancy for the LHCb measurements.

Abstract:
The azimuthal correlations between heavy-flavour hadrons or heavy-flavour decay electrons with charged particles in Pb-Pb collisions give insight on the modification of charm-jet properties in nucleus-nucleus collisions and the mechanisms through which heavy quarks in-medium energy-loss takes place. Studies in pp collisions, besides constituting the necessary baseline for nucleus-nucleus measurements, are important for testing expectations from pQCD-inspired Monte Carlo generators. In ALICE heavy-flavour hadrons are studied via their fully reconstructed hadronic decays (D mesons and Λ c baryon

Abstract:
We review the recent results from the Belle experiment on the measurements of branching fractions and decay asymmetry parameters (α) for the hadronic weak decays of charmed baryons, including Λc+→B+P: Λc+→(Λ,Σ0)h+ (h=π,K) and Λc+→Σ+(π0,η,η′); Ξc0→B+P: Ξc0→Ξ−π+; Ξc0→B+V: Ξc0→ΛK¯*0, Ξc0→Σ0K¯*0, and Ξc0→Σ+K*−. In addition, we present an overview of the searches for CP violation via the α-induced CP asymmetry for Λc+→(Λ,Σ0)h+ and Ξc0→Ξ−π+. Finally, we discuss the promising decay modes of Ωc0 which can be measured in the near future and are indispensable in searching for CP violation in the charm s
