AbstractWe study the up-down asymmetries in the three-body anti-triplet charmed baryon decays of $$\mathbf{B}_{\mathbf{c}}\rightarrow \mathbf{B}_{\mathbf{n}}MM' $$Bc→BnMM′ with the $$SU(3)_f$$SU(3)f flavor symmetry, where $$\mathbf{B}_{\mathbf{c}}$$Bc presents the anti-triplet charmed baryon of $$(\Xi _c^0,-\Xi _c^+,\Lambda _c^+)$$(Ξc0,-Ξc+,Λc+), while $$\mathbf{B}_{\mathbf{n}}$$Bn and $$M^{(')}$$M(′) denote octet baryon and meson states, respectively. By assuming the s-wave meson-pairs to be the dominant constituents in final state configurations, we can write the spin-dependent decay amplitude into parity-conserving and parity-violating parts, parametrized by 6 real parameters under $$SU(3)_f$$SU(3)f, respectively. Fitting these parameters by 16 experimental data points with the minimum $$\chi ^2$$χ2 method, we obtain that $$\chi ^2/d.o.f=2.4$$χ2/d.o.f=2.4. With the fitted parameters, we evaluate the up-down asymmetries along with the decay branching ratios of $$\mathbf{B}_{\mathbf{c}}\rightarrow \mathbf{B}_{\mathbf{n}}MM' $$Bc→BnMM′. Some of these up-down asymmetries are accessible to the experiments at BESIII, BELLE-II and LHCb.

We study the spectra of the doubly charmed tetraquark states in a diquark–antidiquark model. The doubly charmed tetraquark states form an antitriplet and sextet configurations according to flavor SU(3) symmetry. For the tetraquark state [Formula: see text], we show the mass for both bound and excited states. The two-body decays of tetraquark states [Formula: see text] and [Formula: see text] to charmed mesons have also been studied. In the end, the doubly charmed tetraquarks decays to a charmed baryon and a light baryon have been studied in the SU(3) flavor symmetry.

AbstractIn the quark-diagram scheme, we study the charmed baryon decays of $$\mathbf{B}_c\rightarrow \mathbf{B}^* M$$ B c → B ∗ M , where $$\mathbf{B}_c$$ B c is $$\Lambda _c^+$$ Λ c + or $$\Xi _c^{+(0)}$$ Ξ c + ( 0 ) , together with $$\mathbf{B}^*$$ B ∗ (M) the decuplet baryon (pseudoscalar meson). It is found that only two W-exchange processes are allowed to contribute to $$\mathbf{B}_c\rightarrow \mathbf{B}^* M$$ B c → B ∗ M . Particularly, we predict $${\mathcal {B}}(\Lambda _c^+ \rightarrow \Sigma ^{*0(+)} \pi ^{+(0)})=(2.8\pm 0.4)\times 10^{-3}$$ B ( Λ c + → Σ ∗ 0 ( + ) π + ( 0 ) ) = ( 2.8 ± 0.4 ) × 10 - 3 , which respects the isospin symmetry. Besides, we take into account the SU(3) flavor symmetry breaking, in order to explain the observation of $${\mathcal {B}}(\Lambda _c^+\rightarrow \Sigma ^{*+}\eta )$$ B ( Λ c + → Σ ∗ + η ) . For the decays involving $$\Delta ^{++}(uuu)$$ Δ + + ( u u u ) , we predict $${\mathcal {B}}(\Lambda _c^+\rightarrow \Delta ^{++} \pi ^-,\Xi _c^+ \rightarrow \Delta ^{++} K^-) =(7.0\pm 1.4,13.5\pm 2.7)\times 10^{-4}$$ B ( Λ c + → Δ + + π - , Ξ c + → Δ + + K - ) = ( 7.0 ± 1.4 , 13.5 ± 2.7 ) × 10 - 4 as the largest branching fractions in the singly Cabibbo-suppressed $$\Lambda _c^+,\Xi _c^+\rightarrow \mathbf{B}^*M$$ Λ c + , Ξ c + → B ∗ M decay channels, respectively, which are accessible to the LHCb, BELLEII and BESIII experiments.
