Light-quark components analysis and the nature of the $Y (4260)$

Yun-Hua Chen, Ling-Yun Dai, Feng-Kun Guo +1

We study the processes $e^{+} e^{-} \to Y (4260) \to J / ψ π π (K K ˉ)$ . The strong final-state interactions, especially the coupled-channel ( $π π$ and $K K ˉ$ ) final-state interaction…

Predictions of $Υ (4 S) \to h_{b} (1 P, 2 P) π^{+} π^{-}$ transitions

Yun-Hua Chen

In this work, we study the contributions of the intermediate bottomoniumlike $Z_{b}$ states and the bottom meson loops in the heavy quark spin flip transitions $Υ(4S) \to h_b(1P,2P)…

Chromopolarizabilities of bottomonia from the $Υ (2 S, 3 S, 4 S) \to Υ (1 S, 2 S) π π$ transitions

Yun-Hua Chen, Feng-Kun Guo

The dipion transitions $Υ (2 S, 3 S, 4 S) \to Υ (1 S, 2 S) π π$ are systematically studied by considering the mechanisms of the hadronization of soft gluons, exchanging the bottomoniumlike $Z_…

Nature of the $Y (4260)$ : A light-quark perspective

Yun-Hua Chen, Ling-Yun Dai, Feng-Kun Guo +1

The $Y (4260)$ has been one of the most puzzling pieces among the so-called $X Y Z$ states. In this paper, we try to gain insights into the structure of the $Y (4260)$ from the light-q…

Chromopolarizability of charmonium and $π π$ final state interaction revisited

Yun-Hua Chen

The chromopolarizability of a quarknonium describes the quarknonium's interaction with soft gluonic fields and can be measured in the heavy quarkonium decays. Within the framework…
