Description

We report the first observation of a near-threshold enhancement in the D0D0π0 system from B→D0D0π0K decays using a 414 fb-1 data sample collected at the Υ(4S) resonance. The enhancement peaks at a mass M=3875.2±0.7-1.6+0.3±0.8 MeV/c2 and the branching fraction for events in the peak is B(B→D0D0π0K)=(1.22±0.31(+0.23/-0.30))x10-4. The data were collected with the Belle detector at the KEKB energy-asymmetric e+e- collider
