| dc.description.abstract | We analyze two recent reactions of Belle, producing DD¯ and DD¯∗ states that have an enhancement of the invariant DD¯, DD¯∗ mass distribution close to threshold, from the point of view that they might be indicative of the existence of a hidden charm scalar and an axial vector meson states below DD¯ or DD¯∗ thresholds, respectively. We conclude that the data is compatible with the existing prediction of a hidden charm scalar meson with mass around 3700 MeV, though other possibilities cannot be discarded. The peak seen in the DD¯∗ spectrum above threshold is, however, unlikely to be due to a threshold enhancement produced by the presence, below threshold, of the hidden charm axial vector meson X(3872). | |
