Measurement of Heavy-Flavor Properties at CMS and ATLAS

Thanks to the excellent performances of ATLAS and CMS in triggering on muon signals and reconstructing these particles down to low transverse momentum,large samples of heavy-flavored hadrons have been collected in the 2011 LHC run at $\sqrt{s} = 7$ TeV. The analysis of these samples hasenabled both experiments to perform competitive measurements of heavy-flavorproperties, such as quarkonium polarization, lifetime and $CP$-violationmeasurements, hadron spectroscopy and branching ratios of rare $B$ decays
