Abstract

The new parameter Q₀ is introduced in our integration over transverse momenta q_t in perturbative QCD to avoid infrared divergencies. Considering q_t>Q₀, the distribution of wee partons in impact parameter (b_t) and the mean radius of interaction are calculated in the framework of the leading logarithmic approximation (LLA) of perturbative QCD. It is shown that the slope of the elastic amplitude increases as {Mathematical expression}.
