Many models predict that soft interactions will enter a new regime at the
LHC: given the huge energy, unitarization may play a crucial role as the central
part of the protons becomes black [1]. In most part, this depends on the
behaviour of the hadron potential at large distances. Our analysis of dσ/dt of
the TOTEM Collaboration data, carried out without model assumptions, shows
the existence of a new effect (oscillations) in the behavior of the hadron scattering
amplitude at a small momentum transfer at a high confidence level [2].
The quantitative description of the data in the framework of the high energy
generalized structure (HEGS) model supports this phenomenon. The analysis
of the new TOTEM data at 13 TeV in a wide momentum transfer region reveals
an unusual phenomenon - the presence in the elastic scattering amplitude
of a term with a very large slope [3] that is responsible for the behaviour of
hadron scattering at a very small momentum transfer. These phenomena can
be connected with hadron interactions at large distances.
