A measurement of the Bs0→J/ψϕ B_{s}^{0} ightarrow J/psi phi Bs0​→J/ψϕ decay parameters using 80.5 fb−1 80.5, mathrm {fb^{-1}} 80.5fb−1 of integrated luminosity collected with the ATLAS detector from 13 TeV ext {Te} ext {V}TeV proton–proton collisions at the LHC is presented. The measured parameters include the CP-violating phase ϕsphi _{s} ϕs​, the width difference ΔΓs Delta Gamma _{s}ΔΓs​ between the Bs0B_{s}^{0}Bs0​ meson mass eigenstates and the average decay width Γs Gamma _{s}Γs​.
