Radiative decays of $X (3872)$ within $D D ˉ^{*}$ molecular framework

Hao-Dong Cai, Run-Hao Chen, Yuan-Jun Gao +3

Within the framework of nonrelativistic effective field theory, we calculate the radiative decay width of the process $X (3872) \to D ˉ D I^^{3}$ while taking into account the $D\ba…

Role of electromagnetic corrections in the $I ¨ I ¨ $ distributions of $I ¨ ^{'} \to J / I ¨ I ¨ I ¨ $

Zhao-Sai Jia, Gang Li, Zhen-Hua Zhang

The cusp structure at the $I ¨ ^{+} I ¨ ^{-}$ threshold in the $I ¨ ^{0} I ¨ ^{0}$ invariant mass spectrum serves as a sensitive probe for extracting the $S$ -wave $I ¨ I ¨ $ scattering lengths in proces…

Constrain the $I ¨ _{c J} \to D^{()} D ˉ^{()}$ effective couplings via the $X (3872) \to I ¨ ^{0} I ¨ _{c J}$ decays

Zhao-Sai Jia, Gang Li, Zhen-Hua Zhang

The hidden-charm decays serve as irreplaceable platforms for probing the structures of charmonium-like states, such as $X (3872)$ , $Y (4260)$ , $Z_{c} (3900)$ , and their heavy-quark-symm…

Hidden charmed decays of $X (3872)$ within the $D D ˉ^{*}$ molecular framework

Hao-Dong Cai, Zhao-Sai Jia, Gang Li +1

The dipionic transition of the $X (3872)$ to the $I^\cdot_{c}$ was investigated using an effective Lagrangian approach. In this study, the $X (3872)$ was assumed to be a $D\bar{D}^\ast + \t…

Coupled-channel analysis of the near-threshold $e^{+} e^{-} \to N N ˉ$ cross sections

Zhao-Sai Jia, Zhen-Hua Zhang, Feng-Kun Guo +1

The possible existence of nucleon-antinucleon bound states has been studied for decades. We investigate the $e^{+} e^{-} \to p p ˉ$ and $e^{+} e^{-} \to n n ˉ$ cross sections in the nonr…

Pionic transitions of the spin-2 partner of $X (3872)$ to $I ¨ _{c J}$

Shi-Dong Liu, Fan Wang, Zhao-Sai Jia +3

We investigated the pionic transitions between the $X_{2}$ [spin-2 partner of the $X (3872)$ ] and $I ¨ _{c 1, 2}$ using a nonrelativistic effective field theory. The $X_{2}$ is assumed to b…
