Analysis of the hidden-charm tetraquark molecule mass spectrum with the QCD sum rules

High Energy Physics - Phenomenology 2021-10-13 v2

Abstract

In this article, 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 XX, YY, ZZ states in the scenario of tetraquark molecular states consistently based on the QCD sum rules.
