Abstract
We give a complete proof of the existence of scattering amplitudesA(s,t,u) with the following properties
-
i)
the amplitudes are total symmetric ins,t, andu.
-
ii)
they satisfy elastic unitarity for 4≦s≦16, and
-
iii)
they develop resonances forl≧2 on a bounded Regge trajectory which dominates the asymptotics for large energies.
