Dependence of the structure of the elastic scattering amplitude on Mandelstam variables at high energies

Analysis of new experimental data obtained by the TOTEM and ATLAS Collaborations at the LHC together with old data obtained at the SPS and Tevatron colliders at small momentum transferin the framework of the high energy generalized structure (HEGS) model allows one to determine the dependence of different parts of the hadron elastic scattering amplitude on the mandelstam kinematic variables the $s$ and $t$
