We analyse the pp and elastic scattering amplitudes using the data of several CERN and FERMILAB experiments, revisiting ideas proposed by André Martin based on analytic continuation and crossing symmetry. Introducing a new form for the scaling function together with the analytical forms from COMPETE at t = 0 we show that the data are consistent with the crossing symmetry of the scattering amplitudes from 23 GeV to 13 TeV for −t ≤ 0.2 GeV2. Analiticity and crossing symmetry automatically satisfy the dispersion relations and their derivatives. The real part reproduces the zero predicted by Martin, which is crucial to describe with precision the differential cross section in the forward range at high energies. Since the free parameters of the model are energy independent, the analytical form of the amplitude allows predictions for intermediate and higher energies.
