Title: Linear Boltzmann Transport for Jet Propagation in the Quark Gluon Plasma

Speaker: Tan Luo (Central China Normal University)

Abstract:

We develop a Linear Boltzmann Transport model for jet propagation in quark-gluon plasma in high-energy heavy-ion collisions. In this model, we take special consideration of recoiled partons from both elastic scattering and induced gluon radiation processes and their further propagation. Our simulations can provide description of not only the medium modification of the reconstructed jets but also the jet-induced medium excitation in the underlying hydrodynamic background. In this talk, we will discuss various jet observables in single jet and gamma-jets events and compare our results with the experimental data.

To study the jet-medium interaction in detail, we further use the Linear Boltzmann Transport model (LBT model) coupled to (3+1)D ideal hydrodynamic evolution in real time with fluctuating initial conditions to simulate both the transport of jet shower partons and jet-induced medium excitation. In this coupled approach, soft partons from medium recoil and induced radiation from propagation of energetic shower partons in the Linear Boltzmann transport (LBT) model provide a source term to the 3+1D hydrodynamic evolution of the medium, which in term provide medium profile in real time for the parton shower propagation. With this coupled approach we investigate gamma-hadron correlations to study the effect of both jet-induced medium excitations and jet quenching due to parton energy loss.
