Standard Model physics with the ATLAS early data

Standard Model, despite its open questions, has proved its consistency and predictive power to very high accuracy within the currently available energy reach. LHC with its high CM energy and luminosity will give us insight into new processes, possibly showing evidence of "new physics". Excellent understanding of the SM processes will also be a key to discriminate against any new phenomena. Prospects of selected SM measurements with the ATLAS detector using early LHC luminosity will be presented
