Discovering an unquenched dynamics mechanism for charmonium scattering
Abstract
In this paper, we propose a new mechanism for charmonium scattering that utilizes the internal structure of charmonium. By capturing light flavor quarks and antiquarks from the vacuum, charm, and anticharm quarks form virtual charmed mesons, which mediate an effective one-boson exchange process. This approach accurately reproduces the di- J / ψ invariant mass spectrum observed by CMS and LHCb, demonstrating its validity. Our mechanism offers a comprehensive framework for understanding charmonium scattering and is applicable to the scattering problems involving all fully heavy hadrons, an area of increasing interest.
