Query: Medium-induced gluon branching   We study the evolution of an energetic jet which radiates gluons while
propagating through a dense QCD medium modeled as a random distribution of
color sources. Motivated by the heavy ion experimental program at the LHC, we
focus on the medium-induced radiation of (relatively) soft gluons, which are
abundantly emitted at large angles and thus can transport a small fraction of
the jet energy far away from the jet axis. We perform a complete calculation of
the medium-induced gluon branching in the regime where the gluons that take
part in the branching undergo multiple soft scattering with the medium. We
extend the BDMPSZ theory of radiative energy loss by including the transverse
momentum dependence in the kernel that describes the branching and by analyzing
the correlations between the two offspring gluons. We demonstrate that these
gluons lose color coherence with respect to each other over a time scale that
is comparable to the duration of the branching. It follows that interference
effects between successive emissions are suppressed, a necessary ingredient for
a description of multiple emission of soft gluons by a probabilistic, branching
process.
