© 2020 IOP Publishing Ltd.In this paper, one uses the Tsallis entropy (TE) in the impact parameter space to study pp and pp inelastic overlap function and the energy density filling up mechanism responsible by the socalled black disk limit as the energy increases. The TE is non-additive and non-extensive and these features are of fundamental importance since the internal constituents of pp and pp are strongly correlated and also the existence of the multifractal character of the total cross-section. The entropy approach presented here takes into account a phase transition occurring inside the hadrons as the energy increases. This phase transition in the impact parameter space is quite similar to the Berezinskii Kosterlitz Thouless phase transition, possessing also a topological feature due to the multifractal dimension of the total cross-sections in pp and pp scattering..
