| contents | Hidden-charm strong decays of the spin-2 partner $X_2(4014)$ of the charmonium-like state $X(3872)$ have been studied in the framework of the covariant confined quark model. The exotic state $X_2$ has been interpreted as a four-quark state with molecular-type interpolating current. We have considered the decay widths of $X_2$ on the level of two-petal quark loops. The partial widths of the strong decays $X_2\!\to\!ω\, J/Ψ$ and $X_2\!\to\!ρ^0 \, J/Ψ$ have been calculated and the related branching ratio has been analyzed. |
