Abstract
We search for CP-violating charge asymmetries (A(CP)) in the B meson decays to K+/- pi(+/-), K+/- pi(0), K(S)(0)pi(+/-), K+/- eta', and omega pi(+/-). Using 9.66 million Y(4S) decays collected with the CLEO detector, the statistical precision on A(CP) is in the range of +/-0.12 to +/-0.25 depending on decay mode. While CP-violating asymmetries of up to +/-0.5 are possible within the standard model, the measured asymmetries are consistent with zero in all five decay modes studied.
