The ATLAS experiment at the Large Hadron Collider measures CP violation in the neutral Bs0 meson system through the exclusive decay Bs0→J/ψ(μ+μ−)ϕ(K+K−) by analysing time dependent angular correlations of the final state. With 4.9fb−1 of integrated luminosity recorded in 2011 in pp collisions at the LHC at a centre of mass energy of s=7 TeV, first ATLAS results on the values of the CP-violating phase ϕs, the decay width difference ΔΓs as well as other physics parameters of the Bs0 meson decay have been obtained and will be presented here.
