Amplitude analysis of the decay B±→π±π±π

Amplitude analysis of the decay B±→π±π±π

We present a Dalitz-plot analysis of charmless B± decays to the final state π±π±π using 210fb-1 of data recorded by the BABAR experiment at s=10.58GeV. We measure the branching fractions B(B±→π±π±π)=(16.2±1.2±0.9) ×10-6 and B(B±→ρ0(770)π±)=(8.8±1. 0±0.6-0.7+0.1)×10-6. Measurements of branching fract...

Description
Summary:We present a Dalitz-plot analysis of charmless B± decays to the final state π±π±π using 210fb-1 of data recorded by the BABAR experiment at s=10.58GeV. We measure the branching fractions B(B±→π±π±π)=(16.2±1.2±0.9) ×10-6 and B(B±→ρ0(770)π±)=(8.8±1. 0±0.6-0.7+0.1)×10-6. Measurements of branching fractions for the quasi-two-body decays B±→ρ0(1450)π±, B±→f0(980)π± and B±→f2(1270)π± are also presented. We observe no charge asymmetries for the above modes, and there is no evidence for the decays B±→χc0π±, B±→f0(1370)π± and B±→σπ±. © 2005 The American Physical Society.
