The strong coupling gXJ/ψϕ of X(4700)→J/ψϕ in the light-cone sum rules
We assign the scalar tetraquark and the D-wave tetraquark state for X(4700) and calculate the width of the decay X(4700) →J/ψϕ within the framework of light-cone sum rules. The strong coupling gXJ/ψϕ is obtained by considering the technique of soft-meson approximation. We also investigate the mass a...
