Abstract:
In the framework of quantum field theory with de Sitter momentum space an equation
of quasipotential type is obtairmd for a two-particle system. The equation is solved
in the quasictassical approximation. By analogy with the ordinary approach, largeangle
scattering is regarded as scattering by a smooth quasipotential in the region of
classically forbidden angles.
