Abstract:

We show that, within a consistent picture of a Pomeron pole of intercept one which evades the decoupling arguments, total cross-sections should factorise in the energy reǵime where three and more Pomeron cuts are negligible. © 1973.

Abstract:

We investigate pomeron cut contributions in the triple-pomeron limit of one-particle inclusive cross sections, near t = 0 where the triple-pole coupling vanishes. We find that at t = 0 the cuts themselves are suppressed, contributing factors (lnM²)^-2, rather than the single logarithms characteristic of cut contributions in two-body processes. We construct a simple reggeon calculus model in which all important cuts near t = 0 can be calculated, and suggest a simple way of parametrizing the data in that region. © 1973.

Abstract:

We study high energy elastic electron-electron scattering at wide angles in quantum electrodynamics. The amplitude is predicted to decrease exponentially with increasing energy, in agreement with strong interaction data. © 1969.
