Direct $\mathrm{CP}$ violation searches in charmless hadronic B meson decays

We search for direct $\mathrm{CP}$ violation in charmless hadronic B decays observed in a sample of about 22.7 million $B\overline{B}$ pairs collected with the BABAR detector at the SLAC PEP-II asymmetric-energy $e^{+}{e}^{-}$ collider. We measure the following charge asymmetries: ${\mathcal{A}}_{\mathrm{CP}}{(B}^{\pm }\to {\eta }^{\prime }{K}^{\pm })=-0.11\pm 0.11\pm 0.02,$ ${\mathcal{A}}_{\mathrm{CP}}{(B}^{\pm }\to \omega {\pi }^{\pm })=-{0.01}_{\hspace{0.5em}-\hspace{0.5em}0.31}^{\hspace{0.5em}+\hspace{0.5em}0.29}\pm 0.03,$ ${\mathcal{A}}_{\mathrm{CP}}{(B}^{\pm }\to \phi K^{\pm })=-0.05\pm 0.20\pm 0.03,$ ${\mathcal{A}}_{\mathrm{CP}}{(B}^{\pm }\to \phi K^{*\pm })=-{0.43}_{\hspace{0.5em}-\hspace{0.5em}0.30}^{\hspace{0.5em}+\hspace{0.5em}0.36}\pm 0.06,$ and ${\mathcal{A}}_{\mathrm{CP}}(B^0\to \phi K^{*0})=0.00\mathrm{}\pm 0.27\pm \mathrm{0.03.}$
