Abstract

Using a relativized diquark model Hamiltonian, we calculate the masses of JPC=0++ ground-state tetraquarks in the following systems: bsb¯s¯, bbn¯n¯ (n=u,d), bbs¯s¯, ccc¯c¯, bbb¯b¯, bcb¯c¯ and bbc¯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.
