Recent Jet Results in ALICE
ORAL
Abstract
In ultrarelativistic heavy ion collisions quarks and gluons undergo deconfinement forming a hot dense phase of nuclear matter, the Quark Gluon Plasma (QGP). At CERN, in the LHC, a detailed study of the QGP is performed by the ALICE, ATLAS, CMS, and LHCb experiments. At an early time in the collision, high-momentum constituents of the nuclei--partons--scatter off of each other. These initial partons traverse the dense QGP medium and lose energy before exiting and fragmenting into a shower of particles, called a jet. The measurement of in-medium parton energy loss and parton shower modification, collectively referred to as quenching, gives us insight into the structure and interactions that govern the QGP and, ultimately, Quantum Chromodynamics. This talk will report some recent jet results from the ALICE experiment. Measurements from Pb--Pb collisions, where the dense medium is formed, compared to those in p--p collisions, where no medium is formed, indicate that energy loss occurs.
