Abstract
The sum of the and forward elastic scattering amplitudes at high energies is studied from the standpoint of complex angular momentum. Experimental total cross sections and real parts, as well as the Igi sum rule, are used. It is found that excellent fits can be obtained using either two Regge poles (the and the ) or a pole and a cut (the and the ). Two-pole fits indicate that the Pomeranchukon intercept lies in the interval . Prospects for improving these bounds with data at higher energies are investigated.
