Abstract

We search for direct

CP

violation in charmless hadronic B decays observed in a sample of about 22.7 million

B \bar{B}

pairs collected with the BABAR detector at the SLAC PEP-II asymmetric-energy

e^{+} e^{-}

collider. We measure the following charge asymmetries:

A_{CP} {(B}^{\pm} \to η^{'} K^{\pm}) = - 0.11 \pm 0.11 \pm 0.02,

A_{CP} {(B}^{\pm} \to ω π^{\pm}) = - {0.01}_{- 0.31}^{+ 0.29} \pm 0.03,

A_{CP} {(B}^{\pm} \to φ K^{\pm}) = - 0.05 \pm 0.20 \pm 0.03,

A_{CP} {(B}^{\pm} \to φ K^{* \pm}) = - {0.43}_{- 0.30}^{+ 0.36} \pm 0.06,

and

A_{CP} (B^{0} \to φ K^{* 0}) = 0.00 \pm 0.27 \pm 0.03.
