Description

We analyze the mass and width of the doubly heavy tetraquark $T_{ccs}$ ,which consists of a heavy diquark and a light anti-diquark with strangeness. Assuming a color-antitriplet heavy diquark allows us to obtain the mass of $T_{ccs}$ by using the superflavor symmetry and the spectra of $T_{cc}$ reported by LHCb and the singly heavy baryons. We predict the decay width by the effective Lagrangian approach with the SU(3) flavor symmetry. By comparing the obtained results with future experimental data, we can study the color representation of the heavy diquark inside the doubly heavy tetraquark.
