The directed polymer in a 1+3 dimensional random medium is known to present a disorder-induced phase transition. For a polymer of length L, the high temperature phase is characterized by a diffusive behavior for the end-point displacement R<Superscript>2</Superscript> ∼L and by free-energy fluctuations of order ΔF(L)...</superscript>
