A measurement of several properties of the Bs meson, including the CP-violating weak phase phis and the mixing-induced width difference ΔΓs, is performed using the decay Bs → J/ψ(μ+μ−)phi(K+K−), from a dataset of 4.9 fb−1 of integrated luminosity collected in 2011 by the ATLAS detector at the LHC. The measured parameters are consistent with the world average values and theoretical expectations; in particular phis is within 1 σ of the expected value in the Standard Model.
