Analysis of the Hidden-charm Tetraquark molecule mass spectrum with the QCD sum rules
Zhi-Gang Wang
Abstract
In this paper, we investigate the mass spectrum of the ground state hidden-charm tetraquark molecular states without strange, with strange and with hidden-strange via the QCD sum rules in a comprehensive way and revisit the assignments of the [Formula: see text], [Formula: see text], [Formula: see text] states in the scenario of tetraquark molecular states consistently based on the QCD sum rules.
