Results on Standard Model and Heavy Ions physics of the ATLAS collaboration at the LHC

This document presents results of the ATLAS collaboration at the Large Hadron Collider at CERN on Standard Model and Heavy Ions physics. Proton-proton collisions were recorded at an energy sqrt{s} = 7 TeV with a total integrated luminosity of 45 pb-1 in 2010 and up to 1 fb-1 in 2011. Several analysis are presented: the inclusive production cross sections of leptons, photons and jets, the production cross sections for W->lnu, Z/gamma*->ll and cross section measurements of dibosons. Results are compared to the predictions of perturbative QCD calculations and are in good agreement. Lead-lead collisions were recorded at an energy sqrt{s_NN} = 2.76 TeV in 2010 with an integrated luminosity of 9.17 mub-1$. The document reports on the production of W and Z bosons and on an asymmetry in dijet production.
