Roles of $a_{0} (980)^{+} f_{0} (500, 980)$ and $a_{1} (1260)^{+} η$ production mechanisms in decay $D_{s}^{+} \to π^{+} π^{0} π^{0} η$

Jun He

In this work, we theoretically investigate the decay mechanism of $D_{s}^{+} \to π^{+} π^{0} π^{0} η$ based on BESIII data, considering two mechanisms: the production of two dynamically gene…

Virtual state and two-pole structure: $Ξ (1690)$ and $Ξ (1820)$ from BESIII data on $ψ (3686) \to K^{-} Λ Ξ ˉ^{+}$

Jun He

We investigate the nature of the $Ξ (1690)$ and $Ξ (1820)$ resonances by analyzing the recent BESIII data on $ψ (3686) \to K^{-} Λ Ξ ˉ^{+}$ within a coupled-channel rescattering framework…

Role of $Σ^{*} (1/ 2^{-})$ baryons in $Λ_{c} \to Λ π^{+} π^{+} π^{-}$ decay

Jun He

Based on Belle data, the structure around 1435 MeV and the role of the $Σ (1380)$ resonance in the decay process $Λ_{c} \to Λ π^{-} π^{+} π^{+}$ are investigated. The $Λ π^{\pm}$ invariant mass…

Productions of bottom and bottom-strange mesons in pion and kaon induced reactions

Jing Liu, Quan-Yun Guo, Qi Wu +2

In the present work, we propose to explore the productions of the bottom and bottom-strange mesons in the high-energy pion and kaon-induced reactions on a proton target. The cross…
