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…
