We search for CP-violating charge asymmetries ( ACP ) in the B meson decays to K±π∓, K±π0, KS0π±, K±η′, and ωπ±. Using 9.66 million ϒ(4S) decays collected with the CLEO detector, the statistical precision on ACP 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.
