Tetraquark state X(6900) and the interaction between diquark and antidiquark
Abstract Recently LHCb declared a new structure X(6900) in the final state di- $$J/\psi $$ J / ψ which is popularly regarded as a cc- $$\bar{c}\bar{c}$$ c ¯ c ¯ tetraquark state. Within the Bethe–Salpeter (B–S) framework we study the possible cc- $$\bar{c}\bar{c}$$ c ¯ c ¯ bound states and the inter...
