Loops in the Reggeon model for hA scattering

Abstract

Contribution of simplest loops is studied in the Local Reggeon Field Theory with a supercritical pomeron in the nuclear matter. It is shown that the latter transforms the supercritical pomeron into the subcritical. Renormalization of the intercept and difficulties related to the fact that the renormalized intercept is complex are discussed. Numerical results with the conventional parameters are reported.
