Spectrum of fully-heavy tetraquarks from a diquark+antidiquark perspective
2020
European Physical Journal C: Particles and Fields
Using a relativized diquark model Hamiltonian, we calculate the masses of $$J^{PC}=0^{++}$$ J PC = 0 + + ground-state tetraquarks in the following systems: $$b s {\bar{b}} {\bar{s}}$$ b s b ¯ s ¯ , $$bb {\bar{n}} {\bar{n}}$$ b b n ¯ n ¯ ($$n=u, d$$ n = u , d ), $$bb {\bar{s}} {\bar{s}}$$ b b s ¯ s ¯ , $$cc{\bar{c}} {\bar{c}}$$ c c c ¯ c ¯ , $$b b {\bar{b}} {\bar{b}}$$ b b b ¯ b ¯ , $$b c{\bar{b}} {\bar{c}}$$ b c b ¯ c ¯ and $$b b {\bar{c}} {\bar{c}}$$ b b c ¯ c ¯ . We also compute extensive
