Forward Compton Scattering, using Real Analytic Amplitudes

Abstract

We analyze forward Compton scattering, using real analytic amplitudes. By fitting the total γp scattering cross section data in the high energy region 5 GeV < \sqrt s < 20 GeV, using a cross section rising as \ln^2 s, we calculate ρ_{γp}, the ratio of the real to the imaginary portion of the the forward Compton scattering amplitude, and compare this to ρ_{nn}, the ratio of the even portions of the pp and p-bar p forward scattering amplitudes. We find that the two ρ-values are, within errors, the same in the c.m.s. energy region 5 GeV < \sqrt s < 200 GeV, as predicted by a factorization theorem of Block and Kadailov.
