Short range structure in the X(3872)

It is proposed that the newly discovered X(3872) is a J(PC) = 1(++) (D0-D0*) hadronic resonance stabilized by admixtures of omegaJ/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(D) over barD(-0)pi(0), D-0(D) over bar (0)gamma, pi(+)pi(-)J/psi, and pi(+)pi(-)pi(0)J/psi.
