Here, we report the result from the first search for D 0 decays to invisible final states. The analysis is performed on a data sample of 924 fb - 1 collected at and near the Υ ( 4 S ) and Υ ( 5 S ) resonances with the Belle detector at the KEKB asymmetric-energy e + e - collider. The absolute branching fraction is confirmed using an inclusive D 0 sample, obtained by fully reconstructing the rest of the particle system including the other charmed particle. No significant signal yield is observed and an upper limit of 9.4 × 10 - 5 is set on the branching fraction of D 0 to invisible final states at 90% confidence level.
