The modifications that high energy jets experience through their passage across the quark-gluon plasma give us very valuable information about the nature of this high temperature phase of ordinary QCD matter. With the improved statistics of the upcoming heavy ion data from run II at LHC, we will have the opportunity to test the validity of the present models and assess the importance of the several physical phenomena that potentially play a role in the jet/plasma interplay. In this talk I will focus on coherence effects, or how the interferences of the quantum and color correlations among the constituents of a multi partonic system are affected by the presence of a deconfined medium. This has been studied in the literature by the computation of the stimulated gluon emission off a partonic antenna, and the results admit a simple physical interpretation based on the finite resolution power of the plasma (the Debye length for a thin medium). By comparing the relevant scales of the problem one can then determine whether coherence among emitters is lost. The work we have published completes this picture by the computation of the two gluon inclusive in medium emission such that the formation of the antenna itself can be analyzed. By studying the full answer in the different kinematical limits we recover known results and explore new regimes, supporting the idea that from the point of view of the plasma the jet is organised as a collection of effective emitters.
