Abstract

We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million B (B) over bar pairs collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e(+)e(-) collider. We measure the following charge asymmetries: A(CP)(B+/- --> eta'K+/-) = -0.11 +/- 0.11 +/- 0.02, A(CP)(B+/- --> omegapi+/-) = -0.01 +/- (0.29)(0.31) +/- 0.03, A(CP)(B+/- -->phiK+/-)= -00.5 +/-0.20+/-0.03, A(CP)(B+/- --> phiK*=/-)= -0.43 (+0.36)(-0.30) +/-0.06, and A(CP)((B) over bar (0) --> phi(K) over bar*(0)) = 0.00 +/- 0.27 +/- 0.03.
