Nuclear Physics & RIKEN Theory Seminar

"Jet Tomography and Particle Correlations in Heavy-Ion Collisions"

Presented by Barbara Betz, Columbia University

Friday, March 4, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

Heavy-ion collisions offer the possibility to study matter under extreme conditions of high temperatures and densities in the laboratory. Jets and jet-medium correlations can probe the high-energy-density matter created in such collisions.
Azimuthal correlations suggest that conical wakes are induced and have been interpreted as evidence for the creation of Mach cones due to the propagation of a supersonic parton. In this talk, the efforts and the progress in understanding the medium response to the propagation of a
supersonic jet will be critically reviewed and the recent developments will be reported. Moreover, the sensitivity of the azimuthal dependence of single and dihadron nuclear modification factors to the fluctuation spectrum of initial geometric inhomogeneities will be investigated comparing Glauber and KLN Monte Carlo models, leading into a discussion on how average azimuthal moments could help to differentiate between the geometrical ensembles.
