A preliminary analysis of exclusive b → uℓν decays to the final states π ∓ ℓ ± ν, π 0 ℓ ± ν, ρ ∓ ℓ ± ν, ρ 0 ℓ ± ν and ωℓ ± ν based on 2.2 × 10 6 B ¯ B decays collected at CLEO is presented. We have measured the first exclusive b → uℓν branching fraction B(B 0 → π − ℓ + ν) =), with the ISGW (WSB) model used for efficiency determination. A 90% C.L. upper… CONTINUE READING
