Study of γ-jet within a Linear Boltzmann Transport model

The complete set of elastic processes and a higher-twist approach has been implemented in a Linear Boltzmann Transport model for the study of jet-medium interaction. Since the recoiled partons are also taken into account along with the jet shower partons and radiated gluons in this model, we can simulate not only the jet propagation inside the medium but also the medium excitation induced by the jet. In this work, we have discussed various jet observables in gamma-jet events and compare our results with the experimental data. Our results show that the multiple jets are important to include in the calculation of gamma-jet angular distribution. The radius R is extended in our jet shape study to look at the transverse momentum distribution outside the jet cone, where we find that the soft partons from the jet-induced medium excitation dominate.
