“…Theoretical analyses indicate that Dð2550Þ 0 is a good candidate for 2 1 S 0 though the predicted narrow width of 2 1 S 0 is inconsistent with the observation [19][20][21]. D Ã ð2600Þ 0 is interpreted as a mixing state of 2 3 S 1 and 1 3 D 1 [19,20].…”

Possible 2S and 1D excited D and D s states are studied, the charmed states Dð2550Þ 0 , D Ã ð2600Þ, Dð2750Þ 0 , and D Ã ð2760Þ newly observed by the BABAR Collaboration are analyzed. The masses of these states are explored within the Regge trajectory phenomenology, and the strong decay widths are computed within the heavy-quark effective theory. Both the mass and the decay width indicate that Dð2550Þ 0 is a good candidate for 2 1 S 0 . The strong decay property of D Ã ð2600Þ and D Ã s1 ð2700Þ AE is described well by pure 2 3 S 1 states. If a mixing between 2 3 S 1 and 1 3 D 1 does exist, the mixing angle is not large and 2 3 S 1 is predominant. D Ã ð2760Þ and D Ã sJ ð2860Þ AE are possibly the 1 3 D 3 D, and D s , respectively. Dð2750Þ 0 and D Ã ð2760Þ seem two different states, and Dð2750Þ 0 is very possibly the 1Dð2 À ; 5 2 Þ though the possibility of 1Dð2 À ; 3 2 Þ has not been excluded. There may exist an unobserved meson D sJ ð2850Þ AE corresponding to D Ã sJ ð2860Þ AE .

“…In Ref. [10], Zhong studies the strong decays of the Dð2550Þ, Dð2600Þ, and Dð2760Þ in a chiral quark model and identifies the Dð2760Þ as the 1 3 D 3 state and the Dð2600Þ as the low-mass mixing state of the 1 3 D 1 À 2 3 S 1 states.…”

In this article, we study the strong decays of the newly observed charmed mesons Dð2550Þ, Dð2600Þ, Dð2750Þ, and Dð2760Þ with the heavy quark effective theory in the leading order approximation, and tentatively identify the ðDð2550Þ; Dð2600ÞÞ as the 2S doublet ð0 À ; 1 À Þ and the ðDð2750Þ; Dð2760ÞÞ as the 1D doublet ð2 À ; 3 À Þ, respectively. The identification of the Dð2750Þ and Dð2760Þ as the same particle with J P ¼ 3 À is disfavored.

“…In present work we will attempt to understand the inner structure of this newly observed state Ωð2012Þ by analyzing the strong decay properties of its possible candidates within a chiral quark model, so that our theoretical widths can be compared with the measured width directly. The chiral quark model [24] is developed and successfully used to study the Okubo-Zweig-Iizuka (OZI) allowed two-body strong decays of the heavy-light mesons [25][26][27][28] and baryons [29][30][31][32][33][34][35][36]. In this framework, the spatial wave functions of heavy baryons are described by harmonic oscillators, and an effective chiral Lagrangian is then introduced to account for the quark-meson coupling at the baryon-meson interaction vertex.…”

Inspired by the newly observed Ωð2012Þ state at Belle II, we investigate the two-body strong decays of Ω baryons up to N ¼ 2 shell within the chiral quark model. Our results indicate that (i) the newly observed Ωð2012Þ state could be assigned to the spin-parity J P ¼ 3=2 − state j70; 2 10; 1; 1; 3 2 − i and the experimental data can be reasonably described. However, the spin-parity J P ¼ 1=2 − state j70; 2 10; 1; 1; 1 2 − i and spin-parity J P ¼ 3=2 þ state j56; 4 10; 2; 0; 3 2 þ i cannot be completely excluded.(ii) The D-wave states in the N ¼ 2 shell are most likely to be narrow states with a width of dozens of MeV and have a good potential to be observed in the ΞK and/or Ξð1530ÞK channels in future experiments. The Ωð2250Þ resonance listed in PDG may be a good candidate for the J P ¼ 5=2 þ 1D wave state j56; 4 10; 2; 2; 5=2 þ i.
