Tomography of high-energy nuclear collisions with photon-hadron correlations.
Within the next-to-leading order (NLO) perturbative QCD (PQCD) parton model, suppression of away-side hadron spectra associated with a high pT photon due to parton energy loss is studied in high-energy heavy-ion collisions. Because of the sharp falloff of the gamma-jet spectrum in momentum imbalance pTjet-pTgamma>0 in NLO PQCD, hadron spectra at large zT=pTh/pTgamma greater than approximately 1...
متن کاملHigh Energy Nuclear Collisions
Highlights of the results from ultrarelativistic heavy ion collisions at CERN-SPS are reviewed. In particular, I discuss how the experimental results indicate that a collective strongly interacting system has been produced, and what are the implications towards the Quark Gluon Plasma. The physical ideas behind measuring certain observables are introduced. The future program of high energy nucle...
متن کاملEffects of Jet Quenching on High pT Hadron Spectra in High-energy Nuclear Collisions
Assuming an effective energy loss dE/dx for the high ET partons which are produced via hard processes of parton scattering and subsequently propagate through a dense medium, effective jet fragmentation functions are constructed in which leading hadrons will be suppressed. Using such effective fragmentation functions, high pT hadron spectra and particle suppression factors relative to pp collisi...
متن کاملGlauber Modeling in High-Energy Nuclear Collisions
We review the theoretical background, experimental techniques, and phenomenology of what is known in relativistic heavy ion physics as the Glauber model, which is used to calculate geometric quantities. A brief history of the original Glauber model is presented, with emphasis on its development into the purely classical, geometric picture used for present-day data analyses. Distinctions are mad...
متن کاملThermal dileptons in high-energy nuclear collisions
Clear signs of excess dileptons above the known sources were found at the SPS since long. However, a real clarification of these observations was only recently achieved by NA60, measuring dimuons with unprecedented precision in 158A GeV In-In collisions. The excess mass spectrum in the region M<1 GeV is consistent with a dominant contribution from ππ → ρ → μμ annihilation. The associated ρ spec...
