“…The ground-state Ω 0 c has the ss diquark in a J P ¼ 1 þ configuration, and decays weakly. There are no measurements of the absolute branching fractions of the Ω 0 c , but some measurements of the branching ratios of modes with respect to the normalizing mode Ω − π þ have been made [2][3][4]. However, because the production cross section of the Ω 0 c is lower than the other singly charmed baryons, and because it typically decays to more complicated final states, there is less information on its hadronic decays than there is for the other weakly decaying charmed baryons (Λ In this paper, we present the most precise measurements of the branching fractions of Ω 0 c decays into the four decay…”

We report a measurement of the branching fraction and final-state asymmetry for theB 0 → K 0 S K ∓ π ± decays. The analysis is based on a data sample of 711 fb −1 collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider. We obtain a branching fraction of (3.60 ± 0.33 ± 0.15) × 10 −6 and a final-state asymmetry of (−8.5 ± 8.9 ± 0.2)%, where the first uncertainties are statistical and the second are systematic. Hints of peaking structures are seen in the differential branching fractions measured as functions of Dalitz variables.

In this work, we study the localized CP violation in B − → K − π + π − and B − → K − σ(600) decays by employing the quasi two-body QCD factorization approach. Both the resonance and the nonresonance contributions are studied for the B − → K − π + π − decay. The resonance contributions include those not only from [ππ] channels including σ(600), ρ 0 (770) and ω(782) but also from [Kπ] channels including K * (892), K * 0 (1430), K * (1410), K * (1680) and K * 2 (1430). By fitting the experimental data A CP (K − π + π − ) = 0.678 ± 0.078 ± 0.0323 ± 0.007 for m 2 K − π + < 15 GeV 2 and 0.08 < m 2 π + π − < 0.66 GeV 2 , we get the end-point divergence parameters in our model, φ S ∈ [4.75, 5.95] and ρ S ∈ [4.2, 8]. Using these results for ρ S and φ S , we predict that the CP asymmetry parameter A CP ∈ [−0.094, −0.034] and the branching fraction B ∈ [1.82, 20.0] × 10 −5 for the B − → K − σ(600) decay. In addition, we also analyse contributions to the localized CP asymmetry A CP (B − → K − π + π − ) from [ππ], [Kπ] channel resonances and nonresonance individually, which are found to beComparing these results, we can see that the localized CP asymmetry in the B − → K − π + π − decay is mainly induced by the [ππ] channel resonances while contributions from the [Kπ] channel resonances and nonresonance are both very small. Nonleptonic decays of hadrons containing a heavy quark play an important role in testing the Standard Model (SM) picture of the Charge-Parity (CP ) violation mechanism in flavor physics, improving our understanding of nonperturbative and perturbative QCD and exploring new physics beyond the SM. CP violation is related to the weak complex phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix, whichdescribes the mixing of different generations of quarks [1,2]. Besides the weak phase, a large strong phase is also needed for a large CP asymmetry. Generally, this strong phase is provided by QCD loop corrections and some phenomenological models.Three-body decays of heavy mesons are more complicated than the two-body case as they receive resonant and nonresonant contributions and involve three-body matrix elements. The direct nonresonant three-body decay of mesons generally receives two separate contributions: one from the point like weak transition and the other from the pole diagrams that involve three-point or four-point strong vertices.The nonresonant background in charmless three-body B decays due to the transition B → M 1 M 2 M 3 has been studied extensively based on Heavy Meson Chiral Perturbation Theory (HMChPT) [3][4][5]. However, the predicted decay rates are, in general, unexpectedly large and not recovered in the soft meson region.
