“…Parton energy loss can be attributed to both elastic (collisional) [15,16] and inelastic (radiative) [11,12] parton-medium interaction processes. Phenomenological studies of parton energy loss involve sophisticated calculations of the quenching of single inclusive hadron [17][18][19], di-hadron [20][21][22], photon-hadron correlations [23][24][25][26], as well as full jets [26][27][28][29]. Various approaches to parton energy loss have been utilized in these phenomenological applications, and one may refer to Ref.…”

A Linearized Boltzmann Transport (LBT) model coupled with hydrodynamical background is established to describe the evolution of jet shower partons and medium excitations in high energy heavy-ion collisions. We extend the LBT model to include both elastic and inelastic processes for light and heavy partons in the quark-gluon plasma. A hybrid model of fragmentation and coalescence is developed for the hadronization of heavy quarks. Within this framework, we investigate how heavy flavor observables depend on various ingredients, such as different energy loss and hadronization mechanisms, the momentum and temperature dependences of the transport coefficients, and the radial flow of the expanding fireball. Our model calculations show good descriptions of the D meson suppression and elliptic flow observed at the LHC and RHIC. The prediction for the Pb-Pb collisions at √ sNN=5.02 TeV is provided.

“…The tagging bosons escape the region of the hot dense medium unaffected and can be used to constrain the energy of the away-side parton shower. Previous studies of vector boson tagged jet production in heavy ion collisions have been performed in the framework of perturbative QCD [5,6]. A Boltzmann transport model [7], an event generator JEWEL [8] and a hybrid strong/weak coupling model [9] have also been used.…”

Abstract. In these proceedings, we report on recent results related to vector boson-tagged jet production in heavy ion collisions and the related modification of jet substructure, such as jet shapes and jet momentum sharing distributions. Z 0 -tagging and γ-tagging of jets provides new opportunities to study parton shower formation and propagation in the quark-gluon plasma and has been argued to provide tight constrains on the energy loss of reconstructed jets. We present theoretical predictions for isolated photon-tagged and electroweak boson-tagged jet production in Pb+Pb collisions at √ s NN = 5.02 TeV at the LHC, addressing the modification of their transverse momentum and transverse momentum imbalance distributions. Comparison to recent ATLAS and CMS experimental measurements is performed that can shed light on the medium-induced radiative corrections and energy dissipation due to collisional processes of predominantly quark-initiated jets. The modification of parton splitting functions in the QGP further implies that the substructure of jets in heavy ion collisions may differ significantly from the corresponding substructure in proton-proton collisions. Two such observables and the implication of tagging on their evaluation is also discussed.

“…These results indicate that the away-side subleading jets experience significant amount of energy loss when propagating through the produced QGP. Various model calculations based on jet energy loss have been performed to explain the observed dijet and γ-jet momentum imbalance [22,52,53,54,55,56,57,58,59,60,61].…”
