Abstract
We will discuss spin phenomena in elastic processes. A short review consists of four paragraphs: 1. Formalism. First we discuss conservation law and the problem of separation of the kinematics and dynamics. The main result is the introduction of the Dynamic Amplitude for any elastic scattering. 2. Observables. We write out expressions of observables quantities in terms of helicity, invariant and dynamic amplitudes and compare them. 3. High energy behaviour. We obtain Kinematic Hierarchy of contributions of amplitudes in observables. As an example, we consider proton-proton scattering at high energies and large fixed angles ({approx} 90 deg. C). 4. Some applications. We shortly discuss the low-energy theorems, including the case of SUSY particle (gravitino) scattering. Some other possible applications of the formalism (model independent inequalities, dispersion relations, sum rules, and so on) are expounded. (author). 25 refs.
