Prediction of an exotic state around 4240 MeV with $J^{PC}=1^{-+}$ as C-parity partner of Y(4260) in molecular picture

Xiang-Kun Dong, Yong-Hui Lin, Bing-Song Zou

The possibility of the Y(4260) being the molecular state of $D{\bar{D}}_1(2420)+c.c.$ is investigated in the one boson exchange model. It turns out that the potential of $J^{…
