$J / ψ Λ$ femtoscopy and the nature of $P_{ψ s}^{Λ} (4338)$

Yi-Bo Shen, Zhi-Wei Liu, Ming-Zhu Liu +4

Over the past two decades, numerous exotic hadron states have been discovered, yet their underlying nature remains unclear. It is widely acknowledged that understanding hadron-hadr…

$a_{0} (980)$ production, triangle singularity, and non- $ϕ$ background in the $J / ψ \to ϕ η π^{0}$ reaction

Hai-Peng Li, Wei-Hong Liang, Chu-Wen Xiao +1

We study the $J / ψ \to ϕ η π^{0}$ reaction measured recently by the BESIII collaboration with high precision, paying attention to three important aspects: 1) The production of the $a_0(…

Revisiting the $Λ_{c}^{+} \to Λ η π^{+}$ and the roles of intermediate resonances

En Wang, Wen-Tao Lyu, Man-Yu Duan +4

In this paper, we first review the theoretical and experimental studies of the process $Λ_{c}^{+} \to π^{+} η Λ$ . Motivated by the recent BESIII and Belle measurements, we have conducted…

Role of $a_{0} (980)$ in the decays $D^{0} \to K^{+} K^{-} η$ and $π^{+} π^{-} η$

Sara Rahmani, Wei Liang, Yu-Wen Peng +3

In present work, we study the reactions $D^{0} \to K^{+} K^{-} η$ and $D^{0} \to π^{+} π^{-} η$ , and find that the $a_{0} (980)$ state plays a dominant role. At the quar…
