Abstract

The branching fractions and charge asymmeteries in B-meson decays were discussed. The decay amplitudes were evaluated from the measurements of decay rates and CP-violating charge asymmetries. The B-background from charmed and charmless B decays was investigated using MC-simulated events. The uncertainties in the signal MC simulation, which include signal misreconstruction, were evaluated from fully reconstructed B-decays. The misreconstruction signal was due the presence of low momentum pions in the B-decays.
