Abstract
Following a prior analysis of measured pp elastic differential
cross-sections, the impact parameter representation in terms
of profile functions is calculated from two different parametrizations
of single diffractive dissociation data. The derivative of this quantity,
with respect to the collision energy squared s, measures the growth rate of the
reaction's blackness. Its distribution in impact parameter space
allows detailed insight into the growth pattern of the total diffractive cross-section
and the approaching unitarity limit.
Comparing the results with the elastic case, the different mechanisms
of unitarization of two parametrizations are discussed.
