We have tried to measure |Vub| using inclusive semileptonic decay measurements with three different methods. The full reconstruction tag is the one of the most feasible method to measure inclusive process. Semileptonic B→ D(*)ℓν tag is another method to separate signal and tag B mesons. New kinematic variable is used to enhance double semileptonic decays of both B meson. We also improve the neutrino reconstruction technique solving a combination of decay products into signal and tag B mesons using the simulated annealing method.
