Abstract

We report on the observation of B̄→D*π⁺π^-π^-π ⁰ decays. The branching ratios for D*⁺ and D*⁰ are (1.72±0.14±0.24)% and (1.80±0.24±0.27)%, respectively. Each final state has a a D*ωπ^- component, with branching ratios (0.29±0.03±0.04)% and (0.45±0.10±0.07)% for the D*⁺ and D*⁰ modes, respectively. We also observe B̄→Dωπ^- decays. The branching ratios for D⁺ and D⁰ are (0.28±0.05±0.04)% and (0.41±0.07±0.06)%, respectively. A spin parity analysis of the ωπ^- system in the Dωπ^- final state shows a preference for a wide 1^- resonance. A fit to the ωπ^- mass spectrum finds a central mass of (1349 ±25_-5⁺¹⁰) MeV and width of (547±86_-45⁺⁴⁶) MeV. We identify this object as the ρ(1450) or the ρ′.

N2 - We report on the observation of B̄→D*π+π-π-π 0 decays. The branching ratios for D*+ and D*0 are (1.72±0.14±0.24)% and (1.80±0.24±0.27)%, respectively. Each final state has a a D*ωπ- component, with branching ratios (0.29±0.03±0.04)% and (0.45±0.10±0.07)% for the D*+ and D*0 modes, respectively. We also observe B̄→Dωπ- decays. The branching ratios for D+ and D0 are (0.28±0.05±0.04)% and (0.41±0.07±0.06)%, respectively. A spin parity analysis of the ωπ- system in the Dωπ- final state shows a preference for a wide 1- resonance. A fit to the ωπ- mass spectrum finds a central mass of (1349 ±25-5+10) MeV and width of (547±86-45+46) MeV. We identify this object as the ρ(1450) or the ρ′.
