Analysis of the hidden-charm-hidden-strange tetraquark mass spectrum via the QCD sum rules
In the present work, we construct the diquark-antidiquark type four-quark currents to investigate the mass spectrum of the ground state hidden-charm-hidden-strange tetraquark states with the quantum numbers JPC=0++, 1+−, 1++ and 2++ via the traditional QCD sum rules in a comprehensive way. We update...
