| Summary: | In this work we disentangle the underlying physical picture of the in-medium
gluon radiation process across its different energy regimes by comparing the
recently obtained fully-resummed -- without any further approximations --
BDMPS-Z in-medium emission spectrum with the extensively used analytical
approaches. We observe that in the high-energy regime the radiation process is
dominated by a single hard scattering, while in the intermediate-energy region
coherence effects among multiple scatterings are crucial. Finally, we prove
that in the low-energy regime the dynamics is again controlled by a single
scattering but where one must include a suppression factor accounting for the
probability of not having any further scatterings. |
