Will protons become gray at 13 TeV and 100 TeV?

Resumo

It is shown that the regime of pp-interactions at 7 TeV is a critical one. The LHC data about elastic pp-scattering at 7 and 8 TeV are used to get some information about both elastic and inelastic profiles of pp-collisions. They are discussed in the context of two phenomenological models which intend to describe the high energy pp-data with high accuracy. Some predictions following from these models for an LHC energy of 13 TeV and for an energy of 95 TeV of the newly proposed collider are discussed. It is claimed that the center of the inelastic interaction region will become less dark with an increase of energy albeit very slowly.
