All-loop calculations of total, elastic and single diffractive cross   sections in RFT via the stochastic approach
  We apply the stochastic approach to the calculation of the Reggeon Field Theory (RFT) elastic amplitude and its single diffractive cut. The results for the total, elastic and single difractive cross sections with account of all Pomeron loops are obtained.
