Measurement of the CP-violating phase ϕsand the Bs 0meson decay width difference with Bs 0RIGHTWARDS ARROW J/ψϕ decays in ATLAS
Original language description
A measurement of the Bs 0decay parameters in the Bs 0RIGHTWARDS ARROW J/ψϕ channel using an integrated luminosity of 14.3 fbMINUS SIGN 1collected 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 fbMINUS SIGN 1of 7 TeV data& leading to the following: Φs = -0.090 +- 0.078 (stat.) +- (syst.) rad Δ Γs = 0.085 +- 0.011 (stat.) +- 0.007 (syst.) Ps-1 Δ Γs = 0.675 +- 0.003 (stat.) +- 0.03 (syst.) Ps-1 In the analysis the parameter ΔΓs is constrained to be positive. Results for ϕs and ΔΓs are also presented as 68% and 95% likelihood contours in the ϕs-ΔΓs plane. Also measured in this decay channel are the transversity amplitudes and corresponding strong phases. All measurements are in agreement with the Standard Model predictions.
