Parallel Session III: High pT Correlations (I)
- Peter Levai (Hungarian Academy of Sciences (HU))
The PHENIX experiment was designed to excel at measurements of photons.
Direct photons provide a unique tool for measuring jet energy loss, because
they do not participate in the strong interaction and do not lose energy in
the QGP. At leading order the photons are produced with an opposing quark
jet, and the measurement of the photon energy provides a calibrated way to
determine the amount...
A typical approach to study the medium produced in heavy ion collisions is to understand the passage of elementary particles through it. As Z bosons do not participate in the strong interaction, Z+jet production is an important process for the study of the medium-induced energy loss of (predominantly) quark jets. Furthermore, unlike photons, Z bosons are not contaminated by background...
Jet quenching is a powerful tool to study medium properties of relativistic heavy ion collisions via jet-medium interactions. Jet quenching studies have so far focused on high transverse momentum ($p_T$) particle suppression. Jet shapes at low to intermediate $p_T$, containing rich information on jet-medium interactions, have been less explored. Experimentally, jetlike correlations at low...
Heavy-flavor triggered correlations offer a unique sensitivity to study QCD and the QCD medium created in high energy nucleus collisions. Measurement of heavy quark production in p+p collisions allows us to test perturbative QCD calculations and provides a reference for similar studies in heavy-ion collisions. Analysis of heavy-flavor triggered azimuthal correlations and comparisons to light...
