Query: Mapping collinear in-medium parton splittings   We map the spectrum of $1\to 2$ parton splittings inside a medium
characterized by a transport coefficient $\hat q$ onto the kinematical Lund
plane, taking into account the finite formation time of the process. We discuss
the distinct regimes arising in this map for in-medium splittings, pointing out
the close correspondence to a semi-classical description in the limit of hard,
collinear radiation with short formation times. Although we disregard any
modifications of the original parton kinematics in course of the propagation
through the medium, subtle modifications to the radiation pattern compared to
the vacuum baseline can be traced back to the physics of color decoherence and
accumulated interactions in the medium. We provide theoretical support to
vacuum-like emissions inside the medium by delimiting the regions of phase
space where it is dominant, identifying also the relevant time-scales involved.
The observed modifications are shown to be quite general for any dipole created
in the medium.
