AbstractThe compact tetraquark states with fully heavy quark contents QQ (Q) over bar(Q) over bar are studied as the bound states of the diquark-antidiquark within the Bethe-Salpeter framework. The (anti)diquark masses and form factors used are the same as we calculated the doubly heavy baryons in a previous work. Under the instantaneous approximation, the three-dimensional (Bethe-)Salpeter equation of the tetraquarks is derived and solved numerically to obtain the corresponding mass spectra and wave functions of the tetraquarks with J(PC) = 0(++), 1(+-), and 2(++). Our results show that the three ground states of cc (c) over bar(c) over bar locate in the mass range of 6.4-6.5 GeV, and the bb (b) over bar(b) over bar states in mass range of 19.2-19.3 GeV. The obtained relativistic wave functions naturally include the mixing effects from the possible D (or G) partial waves, and then can be further used to do precise calculations of the tetraquark decays. Based on the obtained results, the LHCb's observation X(6900) is less likely to be the ground states of compact cc (c) over bar(c) over bar tetraquarks but might be the first or second excited states. In addition, a widely used propagatorlike form factor is also investigated and discussed.
