Short Range Structure in the X(3872)

Abstract

It is proposed that the newly discovered X(3872) is a $J^{PC}=1^{++}$ $D^0{\bar{D}}^{0\ast }$ hadronic resonance stabilized by admixtures of $\omega J/\psi$ and $\rho J/\psi$. A specific model of the state is constructed and tests of its internal structure are suggested via the predicted decay modes $D^0{\bar{D}}^0{\pi }^0$, $D^0{\bar{D}}^0\gamma$, ${\pi }^{+}{\pi }^{-}J/\psi$, and ${\pi }^{+}{\pi }^{-}{\pi }^{0}J/\psi$.
