Abstract
We investigate the $Y(4260)$ and $Y(4360)$ within the framework of the Faddeev Equations under the fixed center approximation. We find a state of $I=1$ with masses around $4320$ MeV and width about $25$ MeV for the case of $\rho − X(3700)$ and $4256$ MeV for the case of $\bar{D}-D_1(2420)$ with similar width to that of the $\rho − X(3700)$. Hence these states could be associated with the $Y(4260)$ and $Y(4360)$.
