Direct CP violation searches in charmless hadronic B meson decays
Abstract
We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million BBbar pairs collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e+e- collider. We measure the following charge asymmetries: ACP(B+/--->η'K+/-)=-0.11+/-0.11+/-0.02, ACP(B+/--->ωπ+/-)=-0.01 + 0.29 - 0.31+/-0.03, ACP(B+/--->φK+/-)=-0.05+/-0.20+/-0.03, ACP(B+/--->φK*+/-)=-0.43 + 0.36 - 0.30+/-0.06, and ACP(B0-->φK*0)=0.00+/-0.27+/-0.03.
