DECAYS OF HEAVY FLAVOUR HADRONS MEASURED IN CMS AND ATLAS

The ATLAS and CMS data collected in pp collisions during 2010 and 2011 allowed a good quality of B-physics measurements, reproducing essential B-hadron properties, such as masses and lifetimes, and demonstrating a good performance of the two detectors within an increas- ing instantaneous luminosity of the LHC machine. These features enabled in particular a measurement of rare B decays with a precision that contributes to the LHC potential. The CMS and ATLAS results on search for Bs0 → μ+μ−and B0 → μ+μ−decays with 2011 data are reported here.
