  Jet suppression is considered to be an excellent probe of QCD matter created
in ultra-relativistic heavy ion collisions. Our theoretical predictions of jet
suppression, which are based on our recently developed dynamical energy loss
formalism, show a robust agreement with various experimental data, which spans
across different probes, experiments (RHIC and LHC) and experimental conditions
(i.e. all available centrality regions). This formalism includes several key
ingredients, such as inclusion of dynamical scattering centers, finite size QCD
medium, collisional energy loss, finite magnetic mass and running coupling.
While these effects have to be included based on theoretical grounds, it is
currently unclear what is their individual importance in accurately
interpreting the experimental data, in particular because other approaches to
suppression predictions commonly neglect some - or all - of these effects. To
address this question, we here study the relative importance of these effects
in obtaining accurate suppression predictions for D mesons (clear energy loss
probe) at top RHIC and LHC energies. We obtain that several different
ingredients are responsible for the accurate predictions, i.e. the robust
agreement with the data is a cumulative effect of all the ingredients, though
inclusion of the dynamical scattering centers has the largest relative
importance.
