Mixing and CP violation in the decay Bs→J/ψφ in Atlas
A measurement of the B0s→J/ψφ decay parameters, updated to include flavour tagging, is reported using 4.9 fb^{−1} of integrated luminosity collected by the ATLAS detector from pp collisions recorded in 2011. A search for new physics in φs was undertaken by measuring φ_s , the mean lifetime Γ_s and t...
