Jets are hard probes of the medium created in heavy-ion collisions which can provide relevant information about the nature of the quark-gluon plasma. One of the most interesting jet related observables is the energy loss at large angles. This quantity can be described within the BDMPSZ formalism by computing the Markovian evolution of the gluons that form the jet. In this talk I will discuss the event-by-event fluctuations of the energy loss at large angles and the number of gluons and how the results that are found can be related with experimental observables. We derived relations between the fluctuations of the energy loss or the number of gluons and the size of the system and show that, according to our results, the statistics of the number of gluons should fulfil KNO scaling.
