Canonical charmonium interpretation for \textit{Y}(4360) and \textit{Y}(4660)
In this work, we consider the canonical charmonium assignments for Y(4360) and Y(4660). Y(4660) is good candidate of $\rm 5\,^3S_1$ $c\bar{c}$ state, the possibility of Y(4360) as a $\rm 3\,^3D_1$ $c\bar{c}$ state is studied, and the charmonium hybrid interpretation of Y(4360) can not be excluded completely. We evaluate the $e^{+}e^{-}$ leptonic widths, E1 transitions, M1 transitions and the open flavor strong decays of Y(4360) and Y(4660). Experimental tests for the charmonium assignments are suggested. \vskip 0.5cm PACS numbers: 12.39.-x,13.20.Gd, 13.25.Gv,14.40.Lb © 2008 The American Physical Society.
