Heavy Flavor Physics at ATLAS and CMS

Recent results on heavy flavor physics using data from the ATLAS and CMS detectors are presented. The searches for new physics signatures in CP violation of B0_s - anti(B0_s) mixing and in B0_d --> K*0 mu+ mu- decays are discussed. The bottomonium and open-b production results obtained from proton-proton collisions at LHC are shown. The results are based on data samples containing mu+ mu- pairs collected with the ATLAS or CMS detectors by their corresponding muon trigger systems.
