【 摘 要 】

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