ATLAS Higgs Sensitivity for 1fb$^{-1}$ of data at the LHC running at 7 TeV

The Standard Model Higgs discovery potential of ATLAS for each independent final state, such as photon, $W$ and $Z$ boson pairs, as well as for combined channels, is reported. The results based on re-scaling expectations from detailed analysis at 10 or 14 TeV using cross-section ratios are presented for an integrated luminosity for 1fb$^{-1}$ at 7 TeV center of mass energy at the Large Hadron Collider. The discovery potential of a pair of charged Higgs boson and a pseudoscalar Higgs boson introduced by the Minimal Supersymmetric Standard Model is also presented for 1fb$^{-1}$ at 7 TeV.
