Diagnostic Decays of the X(3872)

Abstract

The unusual properties of the X(3872) have led to speculation that it is a weakly bound state of mesons, chiefly $D^0{\bar{D}}^{0\ast }$. Tests of this hypothesis are investigated and it is proposed that measuring the $3\pi J/\psi$, $\gamma J/\psi$, $\gamma {\psi }^{\prime }$, $\bar{K}{K}^{\ast }$, and $\pi \rho$ decay modes of the $X$ will serve as a definitive diagnostic of the molecule hypothesis.
