Form of analyzing power and the determination of the basic parameters of hadron scattering amplitude ”

The determination of magnitudes of basic parameters of the high energy elastic scattering amplitude are examined at small momentum transfers with taking account of the Coulomb-hadron interference effects. An actual problem of the modern elementary particles physics, the research of strong interaction processes at large distances and high energies, is considered in the framework of different approaches by using various models of the structure of hadrons and the dynamics of their interactions. The diffraction scattering cannot yet be described quantitatively in the framework of the perturbative QCD. Therefore, it is necessary to apply different models which can describe the hadron-hadron interaction at large distances. The research of elastic scattering requires the knowledge of properties of the pomeron, the object determining the interaction of hadrons in this range. In this case the study of the structure and spin properties of both the hadron and the pomeron acquires a special role. Now we recognize that the research of the pomeron exchange requires not only a pure elastic process but also many physical processes involving electroweak boson exchanges. There are two approaches to the pomeron, the " soft " pomeron built of multiperipheral hadron exchanges and a more current perturbative-QCD " hard " pomeron built of the gluon-ladder. The " soft " pomeron dominates in high energy hadron-hadron diffractive reactions while the " hard " Pomeron dominates in high energy Υ − Υ scattering [1] and determines the small x-behaviour of deep inelastic structure functions and spin-averaged gluon distributions. The " corner stone " for many models of the Pomeron is the power of the total cross sections growth. The " soft " pomeron of the standard form with α pom (0) = 1 + ǫ was introduced in [2]. The observed growth of inelastic cross sections and the multiplicity match this idea. The perturbative QCD leading log calculation of the gluon ladder di
