A measurement of CP-violating weak phase φs and B 0 s meson decay width difference with B 0 s → J/ψφ decays in the ATLAS experiment is presented. It is based on integrated luminosity of 14.3 fb −1 collected by the ATLAS detector from 8 TeV pp collisions at the LHC. The measured values are statistically combined with those from 4.9 fb −1 of 7 TeV collisions data, yielding an overall Run-1 ATLAS result.
