Heavy Ion Physics with the ATLAS Detector

ATLAS detector is optimized for studies of high-p_T physics in pp collisions at the LHC collider. Preliminary studies show that it is also capable of working in the high multiplicity environment of heavy ion collisions. Available are early measurements of global observables, such as charged particle multiplicity, transverse energy and particle flow, as well as more complex measurements of jet properties and heavy quarkonia production providing crucial information about the properties of matter created in heavy ion collisions at the LHC
