Exclusion of $c\bar c$ Interpretation for $X(3940)$

Partial decay widths of the $X(3940)$ are evaluated in the $^3P_0$ quark model, assuming a charmonium scenario for its structure. In the study all model parameters are predetermined by other reactions. The work reveals that it is difficult to accommodate the $X(3940)$ with any $c\bar c$ meson state in the picture of the potential quark model plus the $^3P_0$ quark dynamics.
