Query: Measurements of Charmless Hadronic B Decays Branching Fraction at BABAR   We present preliminary measurements of the branching fractions for charmless
hadronic decays of B mesons into two-body final states with kaons, pions and a
phi resonance. The measurements are based on a data sample of approximately 23
million B-anti-B pairs collected by the BABAR detector at the PEP-II asymmetric
B Factory at SLAC.
