Measurement of Charge Asymmetries in Charmless Hadronic $\mathit{B}$ Meson Decays

We search for $\mathrm{CP}$-violating charge asymmetries ( $A_{\mathrm{CP}}$ ) in the $B$ meson decays to $K^{\pm }{\pi }^{\mp }$, $K^{\pm }{\pi }^0$, $K_S^0{\pi }^{\pm }$, $K^{\pm }{\eta }^{\prime }$, and $\omega {\pi }^{\pm }$. Using 9.66 million $\Upsilon \left(4S\right)$ decays collected with the CLEO detector, the statistical precision on $A_{\mathrm{CP}}$ is in the range of $\pm 0.12$ to $\pm 0.25$ depending on decay mode. While $\mathrm{CP}$-violating asymmetries of up to $\pm 0.5$ are possible within the standard model, the measured asymmetries are consistent with zero in all five decay modes studied.
