## Connection between fixed-angle and fixed-momentum-transfer scattering in the framework of the double phase representation

The double phase representation of Sugawara and Nambu, which assumes some simple analytical properties with respect to momentum transfer for the phase of the amplitude, is applied to the discussion of large-angle scattering. From the assumptions of Regge behavior and finite asymptotic Regge trajectories, one derives the fixed-angle scaling laws F (s,theta) approx. = s/sup ..delta..//sup F/(theta), and the extrapolation to the large-angle region of the Regge formula; the high-momentum-transfer behavior of Regge residues is thereby obtained. As a byproduct, we get the general form of the amplitude (including its phase) in the large-angle region for given values of ..delta..more »
