摘要：
We present preliminary measurements of branching fractions and direct CP violating asymmetries in charmless twobody B decays, obtained with the BABAR detector using a sample of 227M Upsilon(4S) B (B) over bar decays. We report the first observation of B-0 -> K-0(K) over bar (0) and the first observation of direct CP violation in B-0 -> K(+)pi(-) decays.
