Analytic Amplitude Models for Forward Scattering

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We report on fits of a large class of analytic amplitude models for forward scattering against the comprehensive data for all available reactions. To differentiate the goodness of the fits of many possible parametrizations to a large sample of data, we developed and used a set of quantitative indicators measuring statistical quality of the fits over and beyond the typical criterion of the X2/dof\Chi^2 /dof. These indicators favor models with a universal log2s log^2 s Pomeron term, which enables one to extend the fit down to s=4\sqrt s = 4 GeV.
