Description
Summary:Inspired by the recent observations of the vector charmoniumlike states at BES III Collaboration and ψ(3842) at LHCb Collaboration, we comb the D wave charmonium state in the present work. We first evaluate the possibility of Y(4320) as ψ(33D1) by investigating its open charm decays in the quark-pair creation model and we find the width of Y(4320) can be reproduced in a reasonable parameter range. Moreover, we take ψ(3770), ψ(4160), and Y(4320) as the scale of 1D, 2D, and 3D charmonia to estimate the open charm decays of other D wave charmonia. The total and partial widths of D wave charmonium states have been predicted, which could be tested by further measurements at LHCb and Belle II Collaborations.
