Measurement of B→ρlv decay and |Vub|
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-...
