Proposed mixing between $2 P$ and $1 F$ wave charmonia

Peng-Yu Sun, Tian-Le Gao, Zi-Long Man +1

We investigate $2 P$ - $1 F$ mixing in charmonium, focusing on the close-in-mass $χ_{c 2} (2 P)$ and $χ_{c 2} (1 F)$ states. The conventional tensor force yields negligible mixing, motivatin…

Production of high-spin $ω_{J} / ρ_{J}$ ( $J = 2, 3, 4, 5$ ) mesons in $π^{-} p$ reactions

Ting-Yan Li, Zi-Yue Bai, Xiang Liu

In this work, we perform a comprehensive investigation of the production of high-spin $ω_{J}$ and $ρ_{J}$ mesons ( $J = 2, 3, 4, 5$ ) in $π^{-} p$ reactions using an effective Lagrangian approa…

Radiative decays of the $Ω (2012)$ as a hadronic molecule

Qing-Hua Shen, Jun-Xu Lu, Li-Sheng Geng +2

We present a theoretical investigation of the radiative decay process $Ω (2012) \to γ Ω$ , where the $Ω (2012)$ resonance with spin-parity $J^{P} = \frac{3}{2}^{-}$ , is treated as a dynamica…

Role of $4 S$ - $3 D$ mixing in explaining the $ω$ -like $Y (2119)$ observed in $e^{+} e^{-} \to ρ π$ and $ρ (1450) π$

Zi-Yue Bai, Qin-Song Zhou, Xiang Liu

The BESIII Collaboration has recently reported a new resonance structure in the cross-section analyses of the $e^{+} e^{-} \to ρ π$ and $e^{+} e^{-} \to ρ (1450) π$ processes, displaying charac…

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…

Reevaluating the $ψ (4160)$ Resonance Parameter Using $B^{+} \to K^{+} μ^{+} μ^{-}$ 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 $ψ (4160)$ is pushed higher, presents a challenge to current theoretical models of hadron spectroscopy. This study suggests tha…

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…

Discovery potential of charmonium $2 P$ states through the $e^{+} e^{-} \to γ D D ˉ$ processes

Tian-Le Gao, Ri-Qing Qian, Xiang Liu

In this work, we investigate the production of charmonium $2 P$ states via the $e^{+} e^{-} \to γ D D ˉ$ process at $s = 4.23$ GeV. Using the measured cross-section data for $e^+…
