  "abstract": "<p>The CP -violating asymmetry asls is studied using semileptonic decays of Bs0 and B\u00afs0 mesons produced in pp collisions at a centre-of-mass energy of 7 TeV at the LHC, exploiting a data sample corresponding to an integrated luminosity of 1.0\u00a0fb\u22121 . The reconstructed final states are Ds\u00b1\u03bc\u2213 , with the Ds\u00b1 particle decaying in the \u03d5\u03c0\u00b1 mode. The Ds\u00b1\u03bc\u2213 yields are summed over B\u00afs0 and Bs0 initial states, and integrated with respect to decay time. Data-driven methods are used to measure efficiency ratios. We obtain asls=(\u22120.06\u00b10.50\u00b10.36)% , where the first uncertainty is statistical and the second systematic.</p>",
