Abstract

Using a sample of 3.3×10⁶ Y(4S)→BB̄ events collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR), we measure B(B→ρlv), |V_ub|, and the partial rate (ΔΓ) in three bins of q²≡(p_B -p_ρ)². We find B(B⁰→ρ^-l+v)=(2.69±0.41 _-0.40^+0.35±0.50)×10^-4, |V_ub|=(3.23±0.24_-0.26^+0.23 ±0.58)×10^-3, ΔΓ(0<q²<7 GeV²/c⁴)=(7.6±3.0_-1.2 ^+0.9±3.0)×10^-2 ns^-1, ΔΓ(7<q²<14 GeV²/c⁴)=(4.8 ±2.9_-0.8^+0.7±0.7)×10^-2 ns^-1, and ΔΓ(14<q²<21 GeV²/c⁴)=(7.1±2.1_-1.1 ^+0.9±0.6)×10^-2 ns^-1. Here, l=e or μ, but not both, and the errors are statistical, systematic, and theoretical. The method is sensitive primarily to B→ρlv decays with leptons in the energy range above 2.3 GeV. Averaging with the previously published CLEO results for B→ρlv, we obtain B(B⁰→ρ^-l⁺v)=(2.57±0.29 _-0.46^+0.33±0.41)×10^-4 and |V_ub|=(3.25 ±0.14_-0.29^+0.21±0.55)×10^-3.

N2 - Using a sample of 3.3×106 Y(4S)→BB̄ events collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR), we measure B(B→ρlv), |Vub|, and the partial rate (ΔΓ) in three bins of q2≡(pB -pρ)2. We find B(B0→ρ-l+v)=(2.69±0.41 -0.40+0.35±0.50)×10-4, |Vub|=(3.23±0.24-0.26+0.23 ±0.58)×10-3, ΔΓ(02<7 GeV2/c4)=(7.6±3.0-1.2 +0.9±3.0)×10-2 ns-1, ΔΓ(72<14 GeV2/c4)=(4.8 ±2.9-0.8+0.7±0.7)×10-2 ns-1, and ΔΓ(142<21 GeV2/c4)=(7.1±2.1-1.1 +0.9±0.6)×10-2 ns-1. Here, l=e or μ, but not both, and the errors are statistical, systematic, and theoretical. The method is sensitive primarily to B→ρlv decays with leptons in the energy range above 2.3 GeV. Averaging with the previously published CLEO results for B→ρlv, we obtain B(B0→ρ-l+v)=(2.57±0.29 -0.46+0.33±0.41)×10-4 and |Vub|=(3.25 ±0.14-0.29+0.21±0.55)×10-3.
