AB The CP-violating charge asymmetry in B± →φK± decays is measured in a sample of pp collisions at7 TeV centre-of-mass energy, corresponding to an integrated luminosity of 1.0 fb−1 collected by theLHCb experiment. The result is ACP(B± →φK±) = 0.022 ± 0.021 ± 0.009, where the first uncertainty isstatistical and the second systematic. In addition, a search for the B± →φπ± decay mode is performed,using the B± →φK± decay rate for normalization. An upper limit on the branching fraction B(B± →φπ±) < 1.5×10−7 is set at 90% confidence level.
