Quarkonia studies with early ATLAS data
Amongst the first physics results of the ATLAS detector at LHC will be an analysis of Jpsi and Upsilon production. Even at low luminosity ATLAS will quickly start improving on current quarkonia measurements providing world leading results with around 10 pb-1 of data. The narrow quarkonia resonances will also be used as tools for alignment and calibration of the trigger and tracking systems.
