Abstract:
Geometrical methods of analytic completion are used to enlarge the primitive domain of analyticity of the four-point function inp-space. The results imply, in particular, analyticity of the scattering amplitude in two variables, on the mass shell, near all physical points, as well as analyticity of partial-wave amplitudes ins near the physical points of the right-hand side cut.
