Abstract
Rigorous bounds are established on the absorptive part of the scattering amplitude, A(s,t), for t real and within the Lehman-Martin ellipse. This result is used to prove an upper bound on [dlnA(s,t)/dt]t=0, and to show that A(s,t) cannot have a zero in the region 0 > t > -4t0/(lns)2 for s→∞ (√t0=2mΠ for ΠΠ, ΠN, KN, and NN scattering). No assumption is made about the high-energy behavior of the total cross sections.
