Properties of Hadronic Jets in pp, dAu, and AuAu Collisions at RHIC

Paul Constantin, Iowa State University
Building 6008 Conference Room

Understanding how the Quark Gluon Plasma, a hot QCD state of deconfined quarks and gluons formed in relativistic heavy ion collisions, interacts with a fast parton traveling through it yields important information about its properties. One of the first RHIC results was the strong suppression of high transverse momentum hadrons coming from the fragmentation of such energetic partons, a long expected signature of jet quenching in QGP. Two-particle azimuthal correlations is a method that can go further in the analysis of hadronic jets by studying quantities like shape parameters, conditional yields and fragmentation function. We use it to extract these quantities in vacuum (proton-proton collisions), cold nuclear matter (deuteron-gold collisions), and hot QCD matter (gold-gold collisions), and establish their modification induced by the presence of the QGP.
