We analyze two recent reactions of Belle, producing $D\bar D$ and $D\bar D^*$states that have an enhancement of the invariant $D\bar D$, $D\bar D^*$ massdistribution close to threshold, from the point of view that they might beindicative of the existence of a hidden charm scalar and an axial vector mesonstates below $D\bar D$ or $D\bar D^*$ thresholds, respectively. We concludethat the data is compatible with the existing prediction of a hidden charmscalar meson with mass around 3700 MeV, though other possibilities cannot bediscarded. The peak seen in the $D\bar D^*$ spectrum above threshold is,however, unlikely to be due to a threshold enhancement produced by thepresence, below threshold, of the hidden charm axial vector meson X(3872).

Hidden charm dynamically generated resonances and the $e^+e^-\to J/\psi D \bar D$, $J/\psi D\bar D^*$ reactions
