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

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

The paper studies the mixing between the 2P and 1F charmonium states, finding that coupled‑channel effects can produce sizable mixing angles and predicting two‑photon and two‑gluon…

Production of high-spin $I ¨ _{J} / I ¨ _{J}$ ( $J = 2, 3, 4, 5$ ) mesons in $I ¨ ^{-} p$ reactions

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

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

Radiative decays of the $I^c ◯ (2012)$ as a hadronic molecule

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

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

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

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

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

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

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

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

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

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 I ¨ I ¨ $ and $e^{+} e^{-} \to I ¨ (1450) I ¨ $ processes, displaying ch…
