Abstract

The branching fraction Β(Β⁰→rho;^-e⁺v)=(3.29±0.42±0.47±0.55)x10^-4was measured using isospin constraints and extrapolating to all electron energies according to five different form-factor calculations. The errors are statistical, systematic, and theoretical. The value of |V_ub| determined by the same form-factor calculations is |V_ub|=(3/64±0.22±0.25_-0.56 ^+0.39) X 10^-3.
