Analysis of $Ω_{b}^{-} (b ss)$ and $Ω_{c}^{0} (css)$ with QCD sum rules

Zhi-Gang Wang

In this article, we calculate the masses and the pole residues of the $1/2^{+}$ heavy baryons $Ω_{c}^{0} (css)$ and $Ω_{b}^{-} (b ss)$ with the QCD sum rules. The numerical values $M_{Ω_c^0}=…

Strong decays $Σ^{*} \to Σ π, Λ π$ and related strong coupling constant

Zhi-Gang Wang

In this article, we calculate the strong coupling constant $g$ among the decuplet baryons, the octet baryons and the pseudoscalar mesons in the heavy baryon chiral perturbation the…

Final-state interactions in the decays $B^{0} \to χ_{c 0} K^{* 0}$ and $B^{+} \to χ_{c 0} K^{*+}$

Zhi-Gang Wang

In this article, we study the final-state rescattering effects in the decays $B^{0} \to χ_{c 0} K^{* 0}$ and $B^{+} \to χ_{c 0} K^{*+}$ , and observe the corrections are zero in the SU(3) lim…

Another tetraquark structure in the $π^{+} χ_{c 1}$ invariant mass distribution

Zhi-Gang Wang

In this article, we assume that there exists a scalar hidden charm tetraquark state in the $π^{+} χ_{c 1}$ invariant mass distribution, and study its mass using the QCD sum rules. The…

Possible tetraquark states in the $π^{+} χ_{c 1}$ invariant mass distribution

Zhi-Gang Wang

In this article, we assume that there exist hidden charmed tetraquark states with the spin-parity $J^{P} = 1^{-}$ , and calculate their masses with the QCD sum rules. The numerical result…
