摘要

在协变受限夸克模型的框架下，研究了类谐态X（3872）的自旋2伴子X2（4014）的隐粲强衰变。奇异态X2被解释为具有分子型内插电流的四夸克态。我们在双瓣夸克环的水平上考虑了X2的衰减宽度。计算了强衰变X2→ωJ/Ψ和X2→ρ0J/Ψ的部分宽度，并分析了相应的分支比。2025年由美国物理学会出版

Hidden-charm strong decays of the spin-2 partner of X(3872)

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→ωJ/Ψ and X2→ρ0J/Ψ have been calculated and the related branching ratio has been analyzed.
