A measurement of the B0s?J/?? decay parameters, updated to include flavor tagging is reported using 4.9??fb-¹ of integrated luminosity collected by the ATLAS detector from vs=7??TeV pp collisions recorded in 2011 at the LHC. The values measured for the physical parameters are ?s=0.12±0.25(stat)±0.05(syst)??rad ?Gs=0.053±0.021(stat)±0.010(syst)??ps-¹ Gs=0.677±0.007(stat)±0.004(syst)??ps-¹ |A?(0)|2=0.220±0.008(stat)±0.009(syst) |A0(0)|2=0.529±0.006(stat)±0.012(syst) d?=3.89±0.47(stat)±0.11(syst)??rad where the parameter ?Gs is constrained to be positive. The S-wave contribution was measured and found to be compatible with zero. Results for ?s and ?Gs are also presented as 68% and 95% likelihood contours, which show agreement with the Standard Model expectations.
