# Search for direct CP violation in quasi-two-body charmless B decays

Abstract : We have searched for direct CP violation in quasi-two-body charmless B decays observed in a sample of about 45 million B mesons collected with the BABAR detector at the PEP-II collider. We measure the following charge asymmetries in decay: ${\cal A}_{CP} (B^{\pm}\to\eta^\prime K^{\pm}) = -0.11\pm 0.11\pm 0.02$, ${\cal A}_{CP} (B^{\pm}\to\omega \pi^{\pm}) = -0.01^{+0.29}_{-0.31}\pm 0.03$, ${\cal A}_{CP} (B^{\pm}\to\phi K^{\pm}) = -0.05\pm 0.20\pm 0.03$, ${\cal A}_{CP} (B^{\pm}\to\phi K^{*\pm}) = -0.43^{+0.36}_{-0.30}\pm 0.06$, and ${\cal A}_{CP} (B^{0}/\bar B^{0}\to\phi K^{*0}/\bar K^{*0}) = 0.00\pm 0.27\pm 0.03$.
