Spectrum of fully-heavy tetraquarks from a diquark+antidiquark perspective
Abstract
Using a relativized diquark model Hamiltonian, we calculate the masses of JPC=0++ ground-state tetraquarks in the following systems: b s b ¯ s ¯ , b b n ¯ n ¯ (n =u ,d ), b b s ¯ s ¯ , c c c ¯ c ¯ , b b b ¯ b ¯ , b c b ¯ c ¯ and b b c ¯ c ¯ . We also compute extensive spectra for the fully-heavy quark flavour combinations. Finally, as a test of the diquark model approach, we compute the masses of fully-heavy baryons in the diquark model. Our results may be compared soon to the forthcoming experimental data for fully-heavy three-quark systems.
