Pole analysis on the hadron spectroscopy of $Λ_{b} \to J /Ψ p K^{-}$

Shi-Qing Kuang, Ling-Yun Dai, Xian-Wei Kang +1

In this paper we study the $J /Ψ p$ spectroscopy in the process of $Λ_{b} \to J /Ψ p K^{-}$ . The final state interactions of coupled channel $J /Ψ p$ ~-~ $D ˉ Σ_{c}$ ~-~ $D ˉ^{*} Σ_{c}$ are…

Revisiting $X (3872) \to D^{0} D ˉ^{0} π^{0}$ in XEFT

Lin Dai, Feng-Kun Guo, Thomas Mehen

The calculation of the decay $X (3872) \to D^{0} D ˉ^{0} π^{0}$ in effective field theory is revisited to include final state $π^{0} D^{0}$ , $π^{0} D ˉ^{0}$ and $D^{0} D ˉ^{0}$ rescattering…

Light-quark components analysis and the nature of the $Y (4260)$

Yun-Hua Chen, Ling-Yun Dai, Feng-Kun Guo +1

We study the processes $e^{+} e^{-} \to Y (4260) \to J / ψ π π (K K ˉ)$ . The strong final-state interactions, especially the coupled-channel ( $π π$ and $K K ˉ$ ) final-state interaction…

Nature of the $Y (4260)$ : A light-quark perspective

Yun-Hua Chen, Ling-Yun Dai, Feng-Kun Guo +1

The $Y (4260)$ has been one of the most puzzling pieces among the so-called $X Y Z$ states. In this paper, we try to gain insights into the structure of the $Y (4260)$ from the light-q…

Re-examining the $X (4630)$ resonance in the reaction $e^{+} e^{-} \to Λ_{c}^{+} Λ ˉ_{c}^{-}$

Ling-Yun Dai, Johann Haidenbauer, Ulf-G. Meißner

The reaction $e^{+} e^{-} \to Λ_{c}^{+} Λ ˉ_{c}^{-}$ is investigated at energies close to the threshold with emphasis on the role played by the $X (4630)$ resonance. The interaction in t…

Quarkonium Polarization and the Long Distance Matrix Elements Hierarchies using Jet Substructure

Lin Dai, Prashant Shrivastava

We investigate the quarkonium production mechanisms in jets at the LHC, using the Fragmenting Jet Functions (FJF) approach. Specifically, we discuss the jet energy dependence of th…
