Exploring the role of higher $ω$ meson states in the $e^{+} e^{-} \to b_{1} (1235) π$ process

Zhao-Yang Wu, Zi-Yue Bai, Li-Ming Wang

The properties of light vector mesons near 2.2 GeV remain poorly understood, impeding progress in mapping the higher-lying hadronic spectrum. Utilizing the newly released BESIII da…

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

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

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

Coupled-channel study of $4 S$ - $3 D$ mixing dynamics in $ψ (4220)$ and $ψ (4380)$

Zi-Long Man, Si-Qiang Luo, Zi-Yue Bai +1

Among charmoniumlike $X Y Z$ states, the $ψ (4220)$ and $ψ (4380)$ states have emerged as key candidates for exploring the charmonium spectrum. In this work, we propose a $4 S$ - $3 D$ cha…

Non- $D D ˉ$ Decays into Light Meson Pairs of the $D$ -Wave Charmonium $ψ_{3} (3842)$

Zi-Yue Bai, Bao-Jun Lai, Qin-Song Zou +1

As a $D$ -wave partner of $ψ (3770)$ identified by the LHCb Collaboration, $ψ_{3} (3842)$ lies between the $D D ˉ$ and $D D^{*} ˉ$ thresholds. Its non- $D D ˉ$ decay channels have…

How higher charmonia shape the puzzling data of the $e^{+} e^{-} \to η J / ψ$ cross section

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

Recently, the BESIII collaboration performed a precise measurement of the $e^{+} e^{-} \to η J / ψ$ cross section. It is puzzling that the resonance parameters of the reported $Y (4230)$ sho…
