“…The JETSCAPE Collaboration has developed such a framework for a multi-stage event generator to study and interpret bulk medium, jetquenching, and heavy-flavor measurements in heavy-ion collisions [41]. The JETSCAPE framework has been benchmarked against p + p collisions [42] and used for Bayesian parameter estimation of the bulk properties of the QGP [43][44][45]. An earlier, simplified multi-stage generator was used to carry out a Bayesian evaluation of the jet transport coefficient q [46] [comparing to central and semi-central R AA at RHIC (π 0 at √ s NN = 200 GeV) and the LHC (h ± at √ s NN = 2.76 TeV and 5.02 TeV)].…”

We present a new study of jet interactions in the Quark-Gluon Plasma created in high-energy heavy-ion collisions, using a multi-stage event generator within the JETSCAPE framework. We focus on medium-induced modifications in the rate of inclusive jets and high transverse momentum (high-pT) hadrons. Scattering-induced jet energy loss is calculated in two stages: A high virtuality stage based on the MATTER model, in which scattering of highly virtual partons modifies the vacuum radiation pattern, and a second stage at lower jet virtuality based on the LBT model, in which leading partons gain and lose virtuality by scattering and radiation. Coherence effects that reduce the medium-induced emission rate in the MATTER phase are also included. The T R ENTo model is used for initial conditions, and the (2+1)D VISHNU model is used for viscous hydrodynamic evolution. Jet interactions with the medium are modeled via 2-to-2 scattering with Debye screened potentials, in which the recoiling partons are tracked, hadronized, and included in the jet clustering. Holes left in the medium are also tracked and subtracted to conserve transverse momentum. Calculations of the nuclear modification factor (RAA) for inclusive jets and high-pT hadrons are compared to experimental measurements at RHIC and the LHC. Within this framework,
