Abstract: (Springer)

The results of a search for the narrow P-wave charmed mesons, (DJ), in semileptonic B decays are also reported. Using the decay channels DJ0→D+π−, DJ0→D*+π− and D+J→D0π+ we observe a total signal of 44±8−7+3 DJ0 and 48±10−6+3 DJ+ events. This is the first evidence for semileptonic B decays to charged P-wave charm states. The observed signals also provide evidence for the production of both pseudovector and tensor P-wave charmed mesons in semileptonic B decay. Together these modes are estimated to make up 34±7% of charmed semileptonic B0 and B+ decays.
