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

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

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

Constrain the $χ_{c J} \to D^{()} D ˉ^{()}$ effective couplings via the $X (3872) \to π^{0} χ_{c J}$ 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…

Dihadron Angular Correlations in the $e^{+} e^{-}$ Collision

Wan-Li Ju, Zhe-Yan Shu, Tong-Zhi Yang +2

The precision of fixed-order calculations on the dihadron production in electron-positron annihilation is paramount for probing QCD factorization and constraining non-perturbative…

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…

Production of hidden-heavy and double-heavy hadronic molecules at the $Z$ factory of CEPC

Zhao-Sai Jia, Gang Li, Pan-Pan Shi +1

With a clean environment and high collision energy, the Circular Electron Positron Collider (CEPC) would be an excellent facility for heavy flavor physics. Using the Monte Carlo ev…

Hunting for $X_{b}$ via hidden bottomonium decays $X_{b} \to π π χ_{b J}$

Zhao-Sai Jia, Zhen-Hua Zhang, Wen-Hua Qin +1

In this work, we investigate the isospin breaking decay $X_{b} \to π^{0} χ_{b J}$ and the isospin conserved decay $X_{b} \to π π χ_{b J}$ , where $X_{b}$ is taken to be the heavy quark flavor sy…
