New Global Fit to the Total Photon-Proton Cross-Section sigma L+T and to the Structure Function F2

A fit to world data on the photon-proton cross section sigma L+T and the unpolarised structure function F2 is presented. The 23-parameter ALLM model based on Reggeon and Pomeron exchange is used. Cross section data were reconstructed to avoid inconsistencies with respect to R of the published F2 dat...

Description
Summary:A fit to world data on the photon-proton cross section sigma L+T and the unpolarised structure function F2 is presented. The 23-parameter ALLM model based on Reggeon and Pomeron exchange is used. Cross section data were reconstructed to avoid inconsistencies with respect to R of the published F2 data base. Parameter uncertainties and correlations are obtained.
