Abstract

A measurement of the B0 s → 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 was undertaken by measuring the weak phase φs, the mean lifetime Γs and the lifetime difference ∆Γs.
