Résumé

We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million B B̄ 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 ^±→η′K^±=-0.11±0. 11±0.02, A_CP(B^±→ωπ ^±) = -0.01 _-0.31 ^+0.29±0.03, A_CPB^±→φK^±)= -0.05±0.20±0.03, A_CP(B^± → φK*^±)= -0.43_0.30 ^+0.36±0.06, and A_CP(B⁰→φ K*⁰)=0.00±0.27±0.03.
