Analysis of the Ξ‾ccΞcc hexaquark molecular state with the QCD sum rules
Abstract
In this work, we construct the color-singlet-color-singlet type six-quark pseudoscalar current to investigate the Ξ‾ccΞcc hexaquark molecular state with the QCD sum rules, the predicted mass MX∼7.2GeV supports assigning the X(7200) to be the Ξ‾ccΞcc hexaquark molecular state with the quantum numbers JPC=0−+. The X(7200) can decay through fusions of the c¯c and q¯q pairs, we can search for the X(7200) and explore its properties in the J/ψJ/ψ, χc1χc1, D⁎D¯⁎ and D1D¯1 invariant mass spectrum in the future.
