Abstract
The perturbation theory is shown to be valid for the description of the high-temperature phase of a directed polymer in random medium. The scaling index for the averaged displacement of polymer is calculated for T > TC. The performed summation of main logarithms in (2 + 1)-dimensions indicates the absence of phase transition in such a case.
