First Results from ATLAS on QCD, Quarkonia and Heavy-flavour Physics in p-p collisions at 7TeV

First Results from ATLAS on QCD, Quarkonia, and Heavy-Flavour Physics in proton-proton Collisions at sqrt(s)=7 TeV Content : This talk will give an overview on first results on QCD, quarkonia, and heavy-flavour physics in proton-proton collisions at sqrt(s)=7 TeV, recorded with the ATLAS experiment at the LHC. The QCD measurements address properties of both soft and hard collisions, such as the underlying event, particle production in minimum bias events and jet production. First results from quarkonia and heavy flavour production will be highlighted.
