Study on a power automodel asymptotic behaviour of hadron-hadron scattering at large angles

The phenomenon of a power decrease of differential cross sections of high-energy hadron scattering at large angles in the scope of the quasipotential method is studied. A formal amplitude representation of elastic high-energy scattering at large angles on analytical quasipotentials for scalar particles and particles with spin is found. Scattering cross sections are calculated for identical spinless particles, a scalar particle and two spinor particles. An asymptotic behaviour of nucleon-nucleon scattering amplitudes is studied. Graphical dependences showing an agreement between the data obtained and the experiment for differential cross sections of the π+p-, π-p-, pp-scattering at different energies are presented
