Inverse Inelastic Scattering Theory

Deep Inelastic Scattering — Theory and Phenomenology A

Recent developments in theory and phenomenology relevant to deep inelastic lepton scattering are reviewed, concentrating on the following topics: predicted behaviour of non-singlet and polarized structure functions at small x; theoretical studies of saturation and unitarity effects at small x in quarkonium scattering; renormalons and higher twist contributions; next-to-leading-order calculation...

Deep Inelastic Scattering Beyond Perturbation Theory

I discuss possibilities to observe the instanton-induced contributions to deep inelastic scattering which correspond to nonperturbative exponential corrections to the coefficient functions in front of parton distributions of the leading twist. Talk given at the Leipzig workshop ”Quantum Field Theoretical Aspects of High Energy Physics”, Kyffhäuser, September 20–24, 1993 ∗ On leave of absence fr...

Inequalities in inverse scattering theory

We consider the scattering of time harmonic electromagnetic plane waves by a bounded, inhomogeneous dielectric medium that is partially coated by a thin metallic layer in R. We use far field pattern of the scattered waves at a fixed frequency as data to determine the support D of the inhomogeneous obstacle, the surface conductivity that characterizes the coating and the relative permittivity. N...

Inequalities in Inverse Scattering Theory ∗

Until recently, reconstruction algorithms for solving inverse electromagnetic scattering problems have been based on either nonlinear optimization techniques or on linearized models based on weak scattering approximations [6]. In the past ten years a third approach to reconstruction has been developed which comes under the rubric of qualitative methods in inverse scattering theory, the most pop...
