【 摘 要 】
Flavour changing neutral currents and precision measurements of CP violation are investigated by the ATLAS experiment at the Large Hadron Collider at CERN as probes to physics beyond the Standard Model. This paper presents recent update of flavour tagged time- dependent analysis of Bs→ J/ψ φ, angular analysis of Bd→ K∗μ+μ-and a search for the rare decay B0s→ μ+μ-with measurement of upper limit on its branching fraction. All analyses use 4.9 fb-1of integrated luminosity collected in 2011 at centre-of-mass energy of 7 TeV and the results are in agreement with Standard Model predictions.
