	abstract = {We study the problem of directed polymers in   gaussian environments in $\mathbb{Z}^d$ from the viewpoint of a gaussian family indexed by the set of random walk  paths.  In the zero-temperature case, we give a numerical bound on the maximum of the Hamiltonian, whereas in the finite temperature case, we establish an equivalence between the  "very strong disorder" and the growth rate of the  entropy associated to the model},
