New systematics in hadron total cross section

Analysis of total cross section data from 2 to 200 GeV/c shows striking regularities in the discrepancies between the experimental data and predictions based on two-component duality with exact exchange degeneracy, universality, and SU(3) symmetry. These regularities suggest that the discrepancies are not due to a number of unrelated breaking effects, but are all related and described by a single universal third component which has even-signature isoscalar exchange in the t channel, has exactly the same energy dependence for kaon-nucleon, pion-nucleon, and nucleon-nucleon scattering processes, and scales in the ratio 1 : 2: 9/2. This new component suggests a common origin for the strangeness dependence of the total cross sections and the deviations from quark-model additivity, and gives a unified description of the following apparently unrelated effects: (1) the sigma (πN) - sigma (KN) difference, (2) the deviation of sigma (πN)/sigma (NN) from 2/3, (3) differences in energy behavior of cross sections, particularly the decrease in sigma (pp) at low energies, and (4) the differences between sigma (K+p), sigma (pp), and sigma (phi p) which are all pure Pomeron in two-component duality
