Perspectives of flavor physics at Atlas and CMS

The investigation of heavy-flavor physics represents an alternative approach to direct New Physics searches at Lhc, Atlas and CMS efforts concentrate on decays with muons in the final state, that can be efficiently selected by the multiple-level triggers. In this paper we summarize expected results on different processes, including rare beauty hadron decays, τ decays and q q production, using the data taken in the first years of Lhc running.
