Abstract
We study semileptonic B decay to the exclusive charmless states π, ρ/ω, η, and η′ using the 16fb-1 CLEO Υ(4S) data sample. We find B(B0→π +ν)=(1.37±0.15stat±0.11sys) ×10-4 and B(B0→ρ+ν)=(2.93±0.37stat±0.37sys) ×10-4 and find evidence for B+→η′+ν, with B(B+→η′+ν)=(2.66±0.80stat±0.56sys)×10-4. From our B→πν rate for q2>16GeV2 and lattice QCD, we find |Vub|=(3.6±0.4stat±0.2syst-0.4thy+0.6)×10-3.
