Short Range Structure in the X(3872)

Abstract

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