Abstract

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.
