  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.
