Description
Jet serves as a crucial probe of the Quark-Gluon Plasma (QGP) created in relativistic heavy-ion collisions. While significant efforts have been devoted to developing transport models of jet interactions with the QGP, a simultaneous description of hadron and jet suppression within a unified framework still remains a great challenge. Based on our Linear Boltzmann Transport (LBT) model, we develop a transport approach that tracks the color information of partons during their elastic and inelastic scatterings with the QGP for the first time. This allows us to pause the Pythia vacuum shower of energetic partons at the thermal scale of the QGP, switch to parton transport inside the QGP, and in the end return to Pythia vacuum shower and hadronization outside the color-deconfined medium. Within this new framework, we are able to simultaneously describe the nuclear modification of different species of hadrons and jets, including inclusive and heavy flavor hadrons, as well as inclusive, charged, and heavy flavor jets. Our study highlights the essential role of scales in parton interactions with the QGP, and constructs a consistent picture of jet and hadron suppression in high-energy nuclear collisions.
