Heavy quark dominance in orbital excitation of singly and doubly heavy baryons

Zhen-Yu Li, Guo-Liang Yu, Zhi-Gang Wang +1

A mechanism of the heavy quark dominance in the orbital excitation is proposed in this paper which is testified to be reasonable for singly and doubly heavy baryons. In the relativ…

Analysis of the strong vertices of $Σ_{c} Δ D^{}$ and $Σ_{b} Δ B^{}$ in QCD sum rules

Jie Lu, Guo-Liang Yu, Zhi-Gang Wang +1

In this work, we analyze the strong vertices $Σ_{c} Δ D^{*}$ and $Σ_{b} Δ B^{*}$ using the three-point QCD sum rules under the tensor structures $i ε^{ρ τ α β} p_{α} p_{β}^{'}$ , $p^{ρ} p^{' τ}$ and $p^ρp…

The strong vertices of bottom mesons $B$ , $B^{*}$ and bottomonia $Υ$ , $η_{b}$

Jie Lu, Guo-Liang Yu, Zhi-Gang Wang +1

In this article, the strong coupling constants of vertices $B B Υ$ , $B B^{*} Υ$ , $B^{*} B^{*} Υ$ , $B B^{*} η_{b}$ and $B^{*} B^{*} η_{b}$ are analyzed in the framework of QCD sum rules. In t…
