| [en] We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data (pp, (p) over barp, pip, Kp, gammap, gammagamma, Sigmap). Although these parametrizations are very close for rootsgreater than or equal to9 GeV, it turns out that they differ markedly at low energy, where a universal Pomeron term similar toln(2)s enables one to extend the fit down to roots=4 GeV. | |
