The Leading Light-Cone Singularities and Hadron Collisions

(Received September 4, 1972)
The contribution from the leading light-cone singularities to the total cross sections for γ-hadron and vector meson-hadron collisions is studied by applying the Fourier transformation with time-like momenta to the known part of the current commutator function near the light-cone. The spectral function introduced in the modified causal function is favoured to have a broad spectrum with a finite support. A similar analysis is also made for pseudoscalar meson-hadron collisions. In all cases, the contribution has a common form or structure functions times the spectral function and represents a major part of the continuum in the nondiffractive component. Based on this result, a unique division of the non-diffractive component into the continuum and the resonance-dominated part is suggested in contrast to the duality approach.
