The $1/ N_{c}$ expansion in hadron effective field theory

Guo-Ying Chen

We study the $N_{c}$ scalings of pion-nucleon and nucleon-nucleon scatterings and find that a consistent large $N_{c}$ counting can be established if we assume Witten's counting rules…

Structure of $X_{b}$ from line shape analysis

Yue Ma, Guo-Ying Chen

We study the production line shape of $B^{*} B ˉ$ near threshold, where the $B^{*} B ˉ$ pair comes from the resonance $X_{b}$ . Our study shows that the line shape depends sens…

The nature of $Z_{b}$ states from a combined analysis of $Υ (5 S) \to h_{b} (m P) π^{+} π^{-}$ and $Υ (5 S) \to B^{()} B ˉ^{()} π$

Wen-Sheng Huo, Guo-Ying Chen

With a combined analysis of data on $Υ (5 S) \to h_{b} (1 P, 2 P) π^{+} π^{-}$ and $Υ (5 S) \to B^{(*)} B ˉ^{(*)} π$ in an effective field theory approach, we determine resona…

How to identify the structure of near-threshold states from the line shape

Guo-Ying Chen, Wen-Sheng Huo, Qiang Zhao

We revisit the compositeness theorem proposed by Weinberg in an effective field theory (EFT) and explore criteria which are sensitive to the structure of $S$ -wave threshold states.…

Study of the anomalous cross-section lineshape of e^+e^-\to D\bar D at ψ(3770) with an effective field theory

Guo-Ying Chen, Qiang Zhao

We study the anomalous cross-section lineshape of $e^{+} e^{-} \to D D ˉ$ with an effective field theory. Near the threshold, most of the $D D ˉ$ pairs are from the decay of…
