Abstract

The CP-violating charge asymmetry in B^± → φK^± decays is measured in a sample of pp collisions at 7 TeV centre-of-mass energy, corresponding to an integrated luminosity of 1.0 fb^-1 collected by the LHCb experiment. The result is ACP( B^± → φK^±) = 0.022 ± 0.021 ± 0.009, where the first uncertainty is statistical 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 β(B^± → φπ^± < 1.5 × 10^-7 is set at 90% confidence level. © 2013 The Authors.
