Abstract
The decays B¯0→DsJ+K− and B¯0→DsJ−π+ are studied for the first time. A significant signal is observed in the B¯0→DsJ*(2317)+K− decay channel with B(B¯0→DsJ*(2317)+K−)×B(DsJ*(2317)+→Ds+π0)=(5.3−1.3+1.5±0.7±1.4)×10−5. No signals are observed in the B¯0→DsJ*(2317)−π+, B¯0→DsJ(2460)+K−, and B¯0→DsJ(2460)−π+ decay modes, and upper limits are obtained. The analysis is based on a data set of 140 fb−1 collected by the Belle experiment at the asymmetric e+e− collider KEKB.
