Physics Colloquium, October 11, 2005New frontiers of QCD at RHICDmitri KharzeevBrookhaven National LaboratoryFive years ago, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory started colliding heavy nuclei at record center-of-mass energies of up to 200 GeV/nucleon. Three years from now, the Large Hadron Collider (LHC) at CERN will push the energy of the ions to an astounding 5 TeV/nucleon. What can be learnt from the experiments at these machines? What do we know about the physics of super-dense matter already? I will argue that heavy ion accelerators bring us to new frontiers of physical knowledge, by creating such strong color fields and high densities of partons that qualitatively new phenomena emerge. I will discuss the implications of these results for the physics of strong interactions, astrophysics and cosmology. 3.30 p.m., Robert Smith Seminar Room 1080, PRBRefreshments served at 3:00 p.m., Atrium, PRB |
