Study of the decay B̄0→D*+ωπ-

Abstract:

We report on a study of the decay B̄0→D*+ωπ- with the BABAR detector at the PEP-II B-factory at the Stanford Linear Accelerator Center. Based on a sample of 232×106 BB̄ decays, we measure the branching fraction B(B̄0→D*+ωπ-)=(2.88±0. 21(stat.)±0.31(syst.))×10-3. We study the invariant mass spectrum of the ωπ- system in this decay. This spectrum is in good agreement with expectations based on factorization and the measured spectrum in τ-→ωπ-ντ. We also measure the polarization of the D*+ as a ...
