“…By now, however, it is widely accepted that analytical studies of radiative parton energy loss provide only very limited constraints on phenomenological models implemented in simulation codes [48], mainly because they are restricted to a small part of the relevant kinematics and because they only insufficiently constrain how medium-effects modify the vacuum structure of the parton shower. There have been strong efforts in recent years to overcome these deficiencies in Monte Carlo formulations of medium-modified parton showers [49][50][51][52][53][54][55][56]. Many of these models use parton formation times to specify destructive interference in parton emissions and the spatio-temporal embedding of the parton shower in the medium.…”

We present a conceptually new framework for describing jet evolution in the dense medium produced in ultra-relativistic nucleus-nucleus collisions using perturbative QCD and its implementation into the Monte Carlo event generator Jewel. The rescattering of hard partons in the medium is modelled by infrared continued pQCD matrix elements supplemented with parton showers. The latter approximate higher order realemission matrix elements and thus generate medium-induced gluon emissions. The interplay between different emissions is governed by their formation times. The destructive interference between subsequent scattering processes, the non-Abelian version of the Landau-Pomeranchuk-Migdal effect, is also taken into account. In this way the complete radiation pattern is consistently treated in a uniform way. Results obtained within this minimal and theoretically well constrained framework are compared with a variety of experimental data susceptible to jet-quenching effects at both RHIC and the LHC. Overall, a good agreement between data and simulation is found. This new framework also allows to identify and quantify the dominant uncertainties in the simulation, and we show some relevant examples for this.

Charm quark energy loss in infinite QCD matter using a parton cascade model

We utilize the Parton Cascade Model to study the evolution of charm quarks propagating through a thermal brick of QCD matter. We determine the energy loss and the transport coefficient 'q' for charm quarks. The calculations are done at a constant temperature of 350 MeV and the results are compared to analytical calculations of heavy quark energy loss in order to validate the applicability of using a Parton Cascade Model for the study of heavy quarks dynamics in hot and dense QCD matter.
