Abstract

We report an improved measurement of the branching fraction for B0bar -> DsJ*(2317)+ K- and present evidence of the B0bar -> DsJ(2460)+ K- decay. These results are obtained from a data sample containing 386 million BBbar pairs that was collected near the Y(4S) resonance, with the Belle detector at the KEKB asymmetric energy e+ e- collider.
