Energy evolution of the overlap functions: increasing ratio of ${\sigma }_{el}(s)/{\sigma }_{tot}(s)$ and black ring emergence

Abstract

We analyse the two possible options of the energy dependency of the elastic and inelastic overlap functions. These correspond to saturation of the black disk limit (BEL effect) and to the unitarity saturation (REL effect) at $s\to \infty$. Relation of the REL effect to increase of the ratio ${\sigma }_{el}(s)/{\sigma }_{tot}(s)$ and emergence of black ring picture at the LHC is underlined.
