This work considers cascade trajectories through scales as realizations of a stochastic Langevin process for which multiplicative noise is an intrinsic feature of the turbulent state and selected trajectories are conditioned on their entropy exchange.

It turns out that the integration of fluctuations yields an effective description of the Burgers stochastic dynamics given by the renormalization of its associated heat kernel propagator and the external force-force correlation function.
