Dipion transitions from $X (3872)$ to $χ_{c J} (J = 0, 1, 2)$

Qi Wu, Zhong-Quan Sun, Dian-Yong Chen +2

In this work, we investigate the dipion transition processes $X (3872) \to π π χ_{c J} (J = 0, 1, 2)$ within the framework of heavy hadron chiral perturbation theory, treating $X (3872)$ as…

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…

$Z_{cs}^{+}$ production in the $B^{+}$ decays process

Zhuo Yu, Qi Wu, Dian-Yong Chen

In the present work, we studied the $Z_{cs}^{+}$ exotic state production in the $B^{+}$ meson decays through the meson loop mechanism, where the $B^{+}$ meson decays into an anti-charmed…
