Flavour Tagged Time Dependent Angular Analysis of the $B^0_s\rightarrow J/\psi\phi$ Decay on Run 1 Data in ATLAS

The paper presents the measurement of the $B^0_s$ decay $CP$-violation parameters in the $B^0_s\rightarrow J/\psi\phi$ channel using 14.3 fb$^{-1}$ integrated luminosity collected by the ATLAS detector in $pp$ collisions at $\sqrt{s}=8$ TeV at the LHC. The measured values are statistically combined with those from 4.9 fb$^{-1}$ of $\sqrt{s}=7$ TeV data.
