A measurement of the B0s decay parameters in the B0s  → J/ψϕ channel using an integrated luminosity of 14.3 fb−1 collected by the ATLAS detector from 8 TeV pp collisions at the LHC is presented. The measured parameters include the CP -violating phase ϕs , the decay width Γs and the width difference between the mass eigenstates ΔΓs . The values measured for the physical parameters are statistically combined with those from 4.9 fb−1 of 7 TeV data, leading to the following: ϕs=−0.090±0.078(stat.)±0.041(syst.)radΔΓs=0.085±0.011(stat.)±0.007(syst.)ps−1Γs=0.675±0.003(stat.)±0.003(syst.)ps−1.
