In this work we present our model that dynamically generates resonances fromcharmed and light pseudoscalar and vector mesons. The model generates a richspectrum of charmed and hidden charm scalar and axial resonances, most of themwhich can be associated with observed states. Other states are predicted, inparticular a hidden charm scalar resonance with mass close to the $D\bar D$threshold. For this resonance we present calculations which show that anobserved enhancement in the $D\bar D$ mass spectrum measured by Belle inreactions producing $D\bar D J/\psi$ in the final state could be originated bythis predicted state. We also present theoretical calculations on the radiativedecay width of the $\psi(3770)$ into this state. The predicted branchingfractions suggest that this predicted state could be observed by BES withstatistics of one year run in the $\psi(3770)$ peak.

Testing the predicted dynamically generated hidden charm $X$ scalar  state through the $D\bar D$ invariant mass spectrum and the radiative decay  of the $\psi(3770)$
