We report on the first observation of B̄0→D1(2430)0ω, B̄0→D1(2420)0ω and B̄0→D2*(2460)0ω decays and determination of their rates as well as the fractions of longitudinal polarizations of the ω for these decays. We also discuss improved measurements of the B→DD*s0(2317) branching fractions with a search for isospin partners of the D*s0(2317)+ state, Z0 and Z++. These measurements use a data sample containing 772 million BB̄ events collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider.
