Abstract

We demonstrate that the recent measurement of the cross section line shapes of e⁺e^-→ χ_c0ω can be naturally explained by the molecular picture for Y(4260) where the Y(4260) is treated as a hadronic molecule dominated by DD₁(2420)+c.c. This result is consistent with properties extracted for Y(4260) as the DD₁(2420)+c.c. molecular state in other reactions such as e⁺e^-→ J/ψππ, h_cππ, D D^*π+c.c., and γX(3872).
