We explore the breaking effects of the SU (3) flavor symmetry in the singly Cabibbo-suppressed antitriplet charmed baryon decays of B c → B n M, with B c = ( 0 c , + c , + c ) and B n (M) the baryon (pseudo-scalar) octets. We find that these breaking effects can be used to account for the experimental data on the decay branching ratios of B(In addition, we obtain that, which all receive significant contributions from the breaking effects, and can be tested by the BESIII and LHCb experiments.

“…The alternative approaches for the charmed hadron decays have been shown in Refs. [15][16][17][18][19][20], which take into account the non-factorizable effects. On the other hand, the SU(3) f symmetry has been tested as a useful tool both in the beauty and charmed 1 To calculate the decay amplitude of A, we use the conventions of |π + = −|11 and |K 0 = −| 1 2 1 2 , whereas |π + = |11 and |K 0 = | 1 2 1 2 are taken in Refs.…”

Three-body charmed baryon decays with SU(3) flavor symmetry

We study the three-body anti-triplet B c → B n M M ′ decays with the SU (3) flavor (SU (3) f ) symmetry, where B c denotes the charmed baryon anti-triplet of (Ξ 0 c , −Ξ + c , Λ + c ), and B n and M (M ′ ) represent baryon and meson octets, respectively. By considering only the S-wave M M ′ -pair contributions without resonance effects, the decays of B c → B n M M ′ can be decomposed into irreducible forms with 11 parameters under SU (3) f , which are fitted by the 14 existing data, resulting in a reasonable value of χ 2 /d.o.f = 2.8 for the fit. Consequently, we find that the triangle sum rule of A0 given by the isospin symmetry holds under SU (3) f , where A stands for the decay amplitude. In addition, we predict that B(Λ + c → nπ +K 0 ) = (0.9 ± 0.8) × 10 −2 , which is 3 − 4 times smaller than the BESIII observation, indicating the existence of the resonant states. For the to-be-observed B c → B n M M ′ decays, we compute the branching fractions with the SU (3) f amplitudes to be compared to the BESIII and LHCb measurements in the future.

“…Also, we use a more accurate approach [74] to include SU(4) symmetry-breaking effects in evaluation of meson-baryon strong couplings. To calculate the pole amplitude (W-exchange contributions), we use nonrelativistic approximation [37,75] [70,76] that SU(4) symmetry-breaking could be induced by the variation of a spatial baryon wave function overlap in weak decay amplitude. We find that pole contributions are significantly enhanced upon the inclusion of flavor-dependent effects via |ψ(0)| 2 variation, consequently, we get larger branching ratios for the decays involving W-exchange diagrams.…”

Encouraged by the recent discovery of the Ξ cc baryon, we investigate two-body nonleptonic weak decays of doubly charmed, Ξ cc , baryons. We calculate the branching ratios for Cabibbo-Kobayashi-Maskawafavored and -suppressed modes in factorization and pole model approaches. The preliminary estimates of nonfactorizable W-exchange contributions are obtained using the pole model. We find that the W-exchange contributions to Ξ cc decays, being sizable, cannot be ignored.
