Query: Simple implementation of color coherence for the resumation of soft
  BDMPS-Z gluons   The evolution of QCD jets under the influence of a dense colored medium leads
to the non trivial modification of the gluon emission spectrum. In the multiple
soft scattering regime, for sufficiently large media, soft and wide angle
emissions can be resummed (in the planar limit of QCD) due to the small
formation time of each gluon emission. Similarly to DGLAP evolution, such
cascades correspond to pure Markovian processes and interferences between
partons are neglected. In this strict limit, color coherence effects are
absent. In the vacuum this coherence effect is critical to guarantee that the
shower is angular ordered. In the medium, it is known that such color coherence
effects might play a role in suppressing radiation at intermediate emission
angles. We present a simple procedure to implement color (de)coherence effects
into the in-medium evolution equations obtained in the pure Markovian
approximation. We verify that the result obtained is in accordance with
previous studies regarding the role of in-medium color coherence in the
evolution of the QCD antenna. The new evolution equation incorporates a novel
emission kernel which enforces color coherence between emitters.
