Heavy-Flavor Angular Correlations Measured by the ALICE Experiment

ORAL

Abstract

Heavy-flavor (charm and beauty) quarks are generated primarily via hard scattering processes in high-energy hadronic collisions. Two-particle azimuthal correlations of heavy flavor particles are a differential measurement which allows for the study of the production and jet fragmentation of heavy quarks. By measuring the azimuthal correlation in different transverse momentum (pT) regions, one can study the details of the structure and momentum distribution of particles produced in heavy-flavor jet fragmentation. The azimuthal correlations between electrons from heavy-flavor decays (trigger) and charged hadrons (associated) are studied in varying trigger and associate particle pT regions. A distinguishing feature of heavy ion (such as Pb-Pb) collisions is the production of a possible phase of nuclear matter, called a Quark Gluon Plasma (QGP). By comparing the heavy-flavor and charged hadron azimuthal correlations in different collision systems, we can determine how the heavy-quark production and fragmentation is modified by interactions with the QGP medium. In this talk, the status of this measurement in pp, p-Pb, and Pb-Pb collisions conducted with the ALICE experiment will be presented.
