Unquenched Charmonium and Beyond

Zi-Yue Bai, Dian-Yong Chen, Qi-Huang +3

The year 2024 marked the 50th anniversary of the discovery of the $J / ψ$ particle, which unveiled the charm quark and the charmonium spectrum, instigating the "November Revolution"…

Decoding the role of $I ¨ $ mesonic states for elucidating the $e^{+} e^{-} \to a_{2} (1320) I ¨ $ data and other reactions

Qin-Song Zhou, Zi-Yue Bai, Jun-Zhang Wang +2

Recently, the BESIII Collaboration observed a $I ¨ $ -like structure $Y (2044)$ in $e^{+} e^{-} \to a_{2} (1320) I ¨ $ , suggesting that $Y (2044)$ may be a candidate of vector meson $I ¨ (2 D)$ by com…

Potential of the reaction $e^{+} e^{-} \to p p ˉ I ¨ ^{0}$ for constructing higher $I ¨ $ -meson spectroscopy above 2.4 GeV

Dan Guo, Jun-Zhang Wang, Qin-Song Zhou

The spectrum of light unflavored vector mesons above 2.4 GeV has not yet been firmly established experimentally. In this work, we demonstrate that the process $e^+e^- \to p\bar{p}Ï…

Reevaluating the $I ¨ (4160)$ Resonance Parameter Using $B^{+} \to K^{+} I^¼^{+} I^¼^{-}$ Data in the Context of Unquenched Charmonium Spectroscopy

Tian-Cai Peng, Zi-Yue Bai, Jun-Zhang Wang +1

A puzzling phenomenon, where the measured mass of the $I ¨ (4160)$ is pushed higher, presents a challenge to current theoretical models of hadron spectroscopy. This study suggests th…
