High energy elastic proton collisions due to hadronic interactions happen practically at all admissible values of the four momentum transfer squared t, while at small |t| also the Coulomb interaction contributes. The hitherto description of the effect of both interactions with the help of the complete elastic amplitude proposed by West and Yennie, which is applied in today's analyses of elastic scattering of charged hadrons is, however, not theoretically consistent The full text >>
