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…
