Search For Charged Higgs Bosons Decaying Via H+ -> tau nu in 7 TeV pp Collisions with the ATLAS Detector

This poster summarizes the searches for charged Higgs bosons using an integrated luminosity of up to 5/fb recorded with the ATLAS detector at the LHC at sqrt(s)=7 TeV centre-of-mass energy. The discovery of a charged Higgs boson would be an unambiguous sign of physics beyond the Standard Model. Recent studies are introduced, results are reported and exclusion limits are given as a function of the production cross section and interpreted in the context of the Minimal Supersymmetric extension of the Standard Model.
