Abstract
We report the measurement of an inclusive partial branching fraction for charmless semileptonic decay and the extraction of . Candidates for are identified with a novel reconstruction method based on neutrino reconstruction via missing 4-momentum and a technique called “simulated annealing.” Based on of data taken with the Belle detector, we obtain and determine .
