  Elastic proton-proton scattering is reviewed starting from the results of the
LHC experiments conducted by the TOTEM and ATLAS collaborations, and the HEGS
model and a simple phenomenological parametrisation are compared with the new
data on the differential elastic proton-proton scattering cross section, which
detect a non-exponential behaviour of the differential cross sections in the
first diffraction cone. We consider the influence of various assumptions on the
extraction of the elastic scattering parameters, and on the deduction of the
total cross section.
