The sensitivity to Bs meson mixing phenomena can be significantly improved by distinguishing the initial meson flavour.The flavour tagging techniques used in the ATLAS measurement of the angular amplitudes contributing to Bs→J/ψφ decays are presented using 4.9 fb−1of pp data at √s= 7 TeV from 2011. The methods, their performance and calibration on self-tagged B±→J/ψK± data are shown.
