Query: Hadronic scattering amplitudes: medium-energy constraints on asymptotic
  behaviour   We consider several classes of analytic parametrisations of hadronic
scattering amplitudes, and compare their predictions to all available forward
data (p p, pbar p, pi p, K p, gamma p, gamma gamma, Sigma p). Although these
parametrisations are very close for sqrt(s) > 9 GeV, it turns out that they
differ markedly at low energy, where a universal pomeron term ~log^2(s) enables
one to extend the fit down to sqrt(s)=4 GeV.
