Analysis
This paper investigates the properties of hadronic molecules composed of heavy quarks using the QCD sum rule method. The study focuses on the $J/ψB_{c}^{+}$ and $η_{c}B_{c}^{\ast +}$ states, predicting their mass, decay modes, and widths. The results are relevant for experimental searches for these exotic hadrons and provide insights into strong interaction dynamics.
