Abstract
An analysis including most recent Belle data on X(3872) is performed, using coupled channel Flatté formula. A third sheet pole close to but belowD0D∗0 threshold is found, besides the bound state/virtual state pole discussed in previous literature. The co-existence of two poles near the D0D∗0 threshold indicates that the X(3872) may be of ordinary cc¯23P1 state origin, distorted by strong coupled channel effects. The latter manifests itself as a molecular bound state (or a virtual state).
