Hidden-Charm Strong Decays of the Spin-2 Partner of X(3872) / G.Ganbold, M.A.Ivanov // Physical Review D [Electronic resource]. – 2025. – Vol. 111, No. 1. – P. 014007. – URL: https://doi.org/10.1103/PhysRevD.111.014007. – Bibliogr.: 68.

Hidden-charm strong decays of the spin-2 partner 𝑋2⁡(4014) of the charmoniumlike state 𝑋⁡(3872) have been studied in the framework of the covariant confined quark model. The exotic state 𝑋2 has been interpreted as a four-quark state with molecular-type interpolating current. We have considered the decay widths of 𝑋2 on the level of two-petal quark loops. The partial widths of the strong decays 𝑋2 →𝜔⁢𝐽/Ψ and 𝑋2 →𝜌0⁢𝐽/Ψ have been calculated and the related branching ratio has been analyzed.
