First Results from ATLAS on QCD, Quarkonia and Heavy_Flavour Physics

ATLAS and the LHC are designed primarily to discover new physics such as the Higgs boson. With the first data it is important to measure expected Standard Model physics processes which will form the background to new physics searches. It is necessary to understand QCD processes in this new energy regime and measurements of charged particle production in minimum bias events and jet production are presented here. First results on quarkonia and heavy flavour physics are also highlighted
