“…On the other hand, with the advantage of avoiding the detailed dynamics of QCD, the approach with SU(3) flavor (SU(3) f ) symmetry can relate decay modes in the b and c-hadron decays [22,[28][29][30][31][32][33][34][35][36][37], where the SU(3) amplitudes receive non-perturbative and non-factorizable effects, despite the unknown sources. In this paper, in terms of SU(3) f symmetry, we will examine the semileptonic and non-leptonic two-body B c decays, search for decay modes accessible to experiment, and establish the spectroscopy of the charmed baryon states.…”

“…To study the charmed baryon decays, since the most often used factorization approach in the b-hadron decays [18][19][20] has been demonstrated not to work for the twobody B c → B n M decays [21,22], where B n(c) and M are denoted as the (charmed) baryon and meson, respectively, one has to compute the sub-leading-order contributions or the final state interactions to take into account the non-factorizable effects [23][24][25][26][27], whereas the QCD-based models in the B c decays are not available yet. On the other hand, with the advantage of avoiding the detailed dynamics of QCD, the approach with SU(3) flavor (SU(3) f ) symmetry can relate decay modes in the b and c-hadron decays [22,[28][29][30][31][32][33][34][35][36][37], where the SU(3) amplitudes receive non-perturbative and non-factorizable effects, despite the unknown sources.…”

“…(5.2) agrees with that in ref. [22] by SU(3) f symmetry also. The B c → B ′ n ℓ + ν ℓ decays are forbidden modes, reflecting the fact that the B c and B ′ n states are the uncorrelated anti-symmetric triplet and symmetric decuplet, respectively, which can be viewed as the interesting measurements to test the broken symmetry.…”

Abstract:We study the semileptonic and non-leptonic charmed baryon decays with SU(3) flavor symmetry, where the charmed baryons can be B c = (n denoted as the baryon octet (decuplet), we find that the B c → B ′ n ℓ + ν ℓ decays are forbidden, while theand Ω ++ ccc → Ω + cc ℓ + ν ℓ decays are the only existing Cabibboallowed modes for B ′ c → B ′ n ℓ + ν ℓ , B cc → B ′ c ℓ + ν ℓ , and B ccc → B (′) cc ℓ + ν ℓ , respectively. We predict the rarely studied.3, 4.8±0.5)×10 −3 . For the observation, the doubly and triply charmed baryon decays ofare the favored Cabibboallowed decays, which are accessible to the BESIII and LHCb experiments.

“…[29], the π mass distribution was studied in the + c → π + π decays with the aim of extracting the π scattering lengths. In a recent work [30] the role of the exclusive + c decays into a neutron in testing the flavor symmetry and final-state interaction was investigated. It was shown that the three-body nonleptonic decays are of great interest to explore the final-state interaction in + c decays.…”

Describing the final-state interaction in the chiral unitary approach, we find that the π + η and η invariant mass distributions, up to an arbitrary normalization, show clear cusp and peak structures, which can be associated with the a 0 (980) and (1670) resonances, respectively. The proposed mechanism can provide valuable information on the nature of these resonances and can in principle be tested by facilities such as BEPCII.

Weak decays of antitriplet charmed baryons from the perspective of flavor symmetry

In this work, we carry out a global fit for the two-body weak decays of antitriplet charmed baryons in both SU(3) respected and broken scenarios incorporating all the available data up to date. In the SU(3) irreducible representation approach (IRA), more amplitudes for irreducible representation terms are taken into account and the ranges for their coefficients in each scenarios are predicted. By a comparison among various fitting schemes in this work, experimental data prefer the SU(3) symmetry breaking scenario. Observables of interest, branching fractions and decay asymmetries of all the Cabibbo-favored (CF), singly Cabibbo-suppressed (SCS) and doubly Cabibbo-suppressed (DCS) channels are calculated in the chosen fitting scheme. Most of our predictions are consistent well with experimental data. We further propose more ways to explore the SU(3) symmetry in charmed baryon decays: (i) A clear measurement of branching fraction on CF mode $$ {\Xi}_c^0\to {\Xi}^0{\pi}^0 $$ Ξ c 0 → Ξ 0 π 0 as a large difference exists between SU(3) respected and broken scenarios. (ii) The decay asymmetries of the five yet-to-be measured CF decay modes, $$ {\Xi}_c^0\to {\Lambda}^0{K}_S $$ Ξ c 0 → Λ 0 K S , Σ0KS, Ξ0π0, Ξ0η, Ξ0η′, for their opposite signs in the two different cases. (iii) The future measurement on branching fraction ratios indicated from eq. (2.10) and presented on table 7. An improved measurement for $$ \alpha \left({\Lambda}_c^{+}\to p{K}_S\right) $$ α Λ c + → p K S is called for since predictions from both fittings, including the one in current work and earlier works, and the pole model calculation prefer an opposite sign from previous experimental value. Given branching fractions of most of the CF modes and part of the SCS modes being measured, predictions for the remaining channels, including the DCS modes as well as more decay asymmetries, are anticipated to be checked by the upcoming experiments in BESIII, Belle/Belle-II and LHCb.
