Weak decays that are naturally suppressed in the Standard Model(SM), such as processes with flavour-changing neutral currents, are perfect for indirect searches of new physics. These decays allow us to investigate higher energy ranges with respect to direct searches thus representing a fundamental complementary tool. Results on the ATLAS analysis of the B0s → μ+μ− rare decay will be presented. The ATLAS study of B0d → K∗0μ+μ− is also reported where the parameters AFB and FL are extracted from the angular distribution of the final state. The measurement of the φs phase in the B0s → J/ψ φ system, that can provide probes for physics beyond the SM, is showed too.
