Heavy Ion Physics at the LHCHeavy Ion Physics at the LHC
•Enormous increase in yields of hard probes
Is the created matter the same as at RHIC?
Yes – Possibility for detailed study of QCD matter discovered at RHIC
No – A new challenge for models
•LHC Energy = 30 RHIC Energy
•Gluon Saturation – even at =0

• Comprehensive program with emphasis on hard probes• Program follows increasing luminosity• Pb+Pb for the first few years, expect other ions and p+Pb later
Soft Physics and Global Event Characterization Centrality and good Event Selection – Scaling with Npart, Ncoll Charged Particle Multiplicity – Initial State Gluon Densities Azimuthal Asymmetry (Flow) – Equation of State Spectra + Correlations – Sources, Radial Flow, dE/dx and Quenching
High pT Probes High pT Particles and studies of Jet Fragmentation – Energy Loss and
Modification of Fragmentation Functions. Flavor and Geometry Dependence. Quarkonia (J/, ) and Heavy Quarks – Suppression and Recombination High Energy Photons, Z0, Jet-, Jet-Z0, Multijet Events – Calibrated Measure
