[en] A model of diffraction dissociation is proposed in which the quantum-mechanical interference between the incoming and the out-going wave determines the cross-section. This interference occurs due to the finite life-time of the excited state

[en] The data on diffraction dissociation at high energies are an important tool to extract the bare triple-pomeron coupling r value

[en] The authors show that modern Regge fits to rising cross sections using the Harari-Freund p+f model of diffraction are not consistent with two component duality. If a conventional Pomeron is chosen (dominant j-plane pole plus weak cuts), the resulting f is dual to the resonances plus one-half the background. In contrast, the p - f identity model of diffraction is shown to satisfy a modified form of two component duality

[en] The Heisenberg uncertainty principle is a theoretical postulate which has been validated by the agreement of quantum electrodynamics with experimentation. The postulate is consistent with the wave-packet definition of a particle and with the wave-particle duality concept. An analysis of the Heisenberg principle reveals, however, that the principle can be derived from actual experiments, rather than being postulated, provided an interaction force is assumed to exist between particles. Such novel interaction is universal in nature, and different from any known particle-particle interaction. Once the law of interaction is inferred from the analysis of the experiments which led to the postulation of the Heisenberg principle and is applied to well-known experimental situations, the wave-packet definition of a particle does not need to be called upon in order to determine the behaviour of the particle. Interestingly, in the case of photons, the application of the interaction law yields the same equations, namely Kirchhoff's and Helmholtz', which are obtained when the classical wave interpretation of the nature of light is adopted to explain diffraction and interference phenomena. An experiment of diffraction with statistically independent laser photons is reported which is capable of discriminating between the two models of light, the wave-packet model and the interacting particles model

[en] For the problem of scattering from an N-particle target a recurrence chain of equations is obtained, which for any N allows one to extract a finite number of terms from the Watson series, terms that in the diffraction limit sum up to the Sitenko-Glauber amplitude. It is shown that in this limit the rest of the terms in the series cancel out

[en] The real part of the elastic forward scattering amplitude is examined on the basis of the diffraction dissociation model. In this picture, the positive sign of the real part observed at high energies indicates that Re f(0) is an entirely peripheral effect, a halo. This conclusion agrees with the available experimental data
