Measurement of the CP-violating phase ϕs and the B0s meson decay width difference with B0sJ/ψϕ decays in ATLAS
Original language description
A measurement of the B0s decay parameters in the B0s J/ψϕ channel using an integrated luminosity of 14.3 fb1 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 fb1 of 7 TeV data, leading to the following: ϕs=0.0900.078(stat.)0.041(syst.)radΔΓs=0.0850.011(stat.)0.007(syst.)ps1Γs=0.6750.003(stat.)0.003(syst.)ps1.
