Abstract: Revealing the Details of QCD Energy Loss With Jets: Prospects of ATLAS Heavy Ion Jet
Measurements
We, as young scientists, are on the brink of the last energy frontier in heavy ion
collisions probably in our lifetime. As soon as 2009 the Large Hadron Collider will provide Pb+Pb
collisions at = 5.5 TeV, an impressive factor of 30 above top RHIC energies. Such
an increase in the center-of-mass energy results in a substantial increase in hard processes: jets, direct
photons, etc. Measurements of these hard processes reveal strong medium modifications in heavy ion collisions at
RHIC. However, even with the cornucopia of data ranging from single particle measurements to multiple, high-$p_T$
particle correlations, many details of the energy loss mechanism are currently not well understood. Utilizing the
large acceptance of the ATLAS detector with its unique calorimeter design, direct ($>$ 50 GeV)
jet and photon measurements in the heavy ion environment is possible. In this talk we outline
the possibilities of measuring the details of energy loss o!
f hard probes in dense, hot QCD matter using reconstructed jet and photon-jet measurements with
the ATLAS detector at the LHC.
