Latest results on flavour physics from ATLAS

Recent results on heavy flavour physics using data from the ATLAS detector are presented. J/ψ+ associated W±, ψ(2S)→J/ψπ+π−, χc1 & χc2 and B+→J/ψK+ production results are shown as well as the results of analyses of , and decays. All measurements are based on data collected with the ATLAS detector at the Large Hadron Collider in pp collisions at a centre of mass energy .
