Distinguishing cusp effects and near-threshold-pole effects

Zhi-Yong Zhou, Zhiguang Xiao

We make use of a unitarized coupled-channel model to analyze the mass distribution data of final states in production processes of $X (4260)$ . By analyzing the analytical structures…

Twist-3 fragmentation functions in a spectator model with gluon rescattering

Zhun Lu, Ivan Schmidt

We study the twist-3 fragmentation functions $H$ and $H ~$ , by applying a spectator model. In the calculation we consider the effect of the gluon rescattering at one loop lev…

Could the $X (3915)$ and the $X (3930)$ Be the Same Tensor State?

Zhi-Yong Zhou, Zhiguang Xiao, Hai-Qing Zhou

By using a combined amplitude analysis of the $γ γ \to D D ˉ$ and $γ γ \to J / ψ ω$ data, we demonstrate that the $X (3915)$ , which is quoted as a $J^{P C} = 0^{++}$ state…
