Description

Processes involving the FCNC transitions in b-hadron decays are suppressed in the SM and are sensitive to new physics. New results in the search for the rare decays of Bs and Bd into mu+mu- are presented. They are based on the full sample of data collected by ATLAS at 7 and 8 TeV of collision energy. The consistency with the SM and with other available measurements is discussed. The properties of the decay of the Bd meson into K*mu+mu- are relevant because of possible deviations from the standard model observed by LHCb. We present recent results obtained by ATLAS, concerning the angular distribution parameters FL, S_i and P_i in the region Q^2(mu+mu-)<6 Gev^2,
