AB The CP-violating asymmetry assl is studied using semileptonic decays of B0sand B0smesons produced inpp collisions at a centre-of-mass energy of 7 TeV at the LHC, exploiting a data sample correspondingto an integrated luminosity of 1.0 fb−1. The reconstructed final states are D±s μ∓, with the D±s particledecaying in the φπ± mode. The D±s μ∓ yields are summed over B0sand B0sinitial states, and integratedwith respect to decay time. Data-driven methods are used to measure efficiency ratios. We obtain assl=(−0.06±0.50±0.36)%, where the first uncertainty is statistical and the second systematic.
