Analytic parametrizations of the non-perturbative Pomeron and QCD-inspired models by Nicolescu, B.; Cudell, J. R.; Ezhela, V. V.; Gauron, P.; Kang, K.; Kuyanov, Yu. V.; Lugovsky, S. B.; Tkachenko, N. P. is a scholarly article available to read on EtoBox.

What is Analytic parametrizations of the non-perturbative Pomeron and QCD-inspired models about?

We consider several classes of analytic parametrizations of hadronic scattering amplitudes, and compare their predictions to all available forward data (proton- proton, antiproton-proton, pion-proton, kaon-proton, photon-proton, photon- photon, sigma-proton). Although these parametrizations are very close for energy larger than 9 GeV, it turns out that they differ markedly at low energy, where a universal Pomeron term ~(ln s)**2 enables one to extend the fit down to 4 GeV.
