In-Medium Properties of Jets
Modifications of jet-like azimuthal correlations have revealed novel
properties of the medium created in relativistic heavy-ion collisions.
Experimental results on jet-like 2- and 3-particle correlations, specificly
"punch-through" at high transverse momentum, broadening at low and modest
transverse momentum, and particularly the possible experimental evidence for
conical flow, are reviewed. Future prospects of jet-like correlations and their
physics potential are discussed.Comment: Invited talk at Quark Matter 200
Supersonic Jets in Relativistic Heavy-Ion Collisions
Mach-cone shock waves were proposed to explain the broad and perhaps
double-peaked away-side 2-particle jet-correlations at RHIC; however, other
mechanisms cannot be ruled out. Three-particle jet-correlation is needed in
order to distinguish various physics mechanisms. In this talk the 3-particle
jet-correlation measurements are presented and their implications are
discussed.Comment: 3 figures. Proceedings of "Quark Confinement and the Hadron Spectrum

Na49 Results on Single Particle and Correlation Measurements in Central PB+PB Collisions
Single-particle spectra and two-particle correlation functions measured by
the NA49 collaboration in central Pb+Pb collisions at 158 GeV/nucleon are
presented. These measurements are used to study the kinetic and chemical
freeze-out conditions in heavy ion collisions. We conclude that large baryon
stopping, high baryon density and strong transverse radial flow are achieved in
central Pb+Pb collisions at the SPS.Comment: Latex file, 12 pages, 5 figures. Invited talk given at the "XXVIII
