A quark model study of strong decays of $X\left(3915\right)$

Abstract

Strong decays of $X\left(3915\right)$ are analyzed from two quark model descriptions of $X\left(3915\right)$, a conventional one in terms of the Cornell potential and an unconventional one from a Generalized Screened potential. We conclude that the experimental suppression of the OZI allowed decay $X\left(3915\right)\to D\overline{D}$ might be explained in both cases as due to the momentum dependence of the decay amplitude. However, the experimental significance of the OZI forbidden decay $X\left(3915\right)\to \omega J/\psi$ could favor an unconventional description.
