Abstract
Inclusive cross sections are discontinuities across certain cuts in the connected parts of appropriate multiparticle scattering amplitudes. This relationship, which is shown here to follow formally from field theory, is analogous to the well-known connection between total cross sections and total discontinuities. It has been used in recent work on the theory of high-energy reactions.Keywords
