  A model for the parton distributions of hadrons in impact parameter space has
been constructed using soft gluon summation. This model incorporates the
salient features of distributions obtained from the intrinsic transverse
momentum behaviour of hadrons. Under the assumption that the intrinsic
behaviour is dominated by soft gluon emission stimulated by the scattering
process, the b-spectrum becomes softer and softer as the scattering energy
increases. In minijet models for the inclusive cross-sections, this will
counter the increase from $\sigma_{jet}$ .
