  In hadron interactions at the LHC energies, the reflective scattering mode
starts to play a role which is expected to be even a more significant beyond
the energies of the LHC. This new but still arguable phenomenon implies a
peripheral dependence of the inelastic probability distribution in the impact
parameter space and asymptotically evolving to the black ring. As a
consequence, the straightforward extension to hadrons of the centrality
definition adopted for nuclei needs to be modified.
