Tetraquark molecular states in the Ds(D)over-bars1, and Ds*(D)over-bars0* mass spectrum

In this work, we construct the color-singlet-color-singlet type four-quark currents to investigate the D-s(D) over bar (s1), and D-s*(D) over bar (s0)* so tetraquark molecular states with the J(PC) = 1(--) and 1(-+) via the QCD sum rules and obtain satisfactory results. We can search for the D-s(D) over bar (s1), and D-s*(D) over bar (s0)* so tetraquark molecular states with the J(PC) = 1(--) and 1(-+) at the BESIII and Belle II in the future.

Automated summary

The study constructed four-quark currents and obtained satisfactory results using QCD sum rules, aiming to search for tetraquark molecular states in the future at BESIII and Belle II.
