Abstract

A measurement of the B0s→J/ψϕ decay parameters, updated to include flavor tagging is reported using 4.9  fb−1 of integrated luminosity collected by the ATLAS detector from s√=7  TeV pp collisions recorded in 2011 at the LHC. The values measured for the physical parameters are

where the parameter ΔΓs is constrained to be positive. The S-wave contribution was measured and found to be compatible with zero. Results for ϕs and ΔΓs are also presented as 68% and 95% likelihood contours, which show agreement with the Standard Model expectations.
