Investigating full-heavy tetraquarks composed of $$cc{\bar{c}}{\bar{b}}$$ and $$bb{\bar{b}}{\bar{c}}$$

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in this work. There is no bound state for systems $$ IJ^{P}=00^{+},01^{+}$$ I J P = 00 + , 01 02^{+}$$ 02 channels. However, system, three possible resonance states with energy of 10{,}079~\textrm{MeV} 10 079 MeV , 10{,}081~\textrm{MeV} 081 10{,}177~\textrm{MeV} 177 found respectively, their decay width \Gamma Γ 6.7–8.4 MeV, 1.4–7.2 MeV 9.1–11.1 MeV. For there also exist 16{,}474~\textrm{MeV} 16 474 16{,}541~\textrm{MeV} 541 the widths them 2.2–6.1 2.2–6.9 5.3–8.5 $$bc{\bar{c}}{\bar{c}}$$ $$cb{\bar{b}}{\bar{b}}$$ will have same results as respectively. These worthy to be searched future experiments.
