Abstract
AbstractWe study the scaling properties of the differential cross section of elastic proton–proton (pp) and proton–antiproton ($$p\bar{p}$$

. We complete this work with a model-dependent evaluation of the domain of validity of the new scaling and its violations. We find that the H(x) scaling is valid, model dependently, within $$200~\hbox {GeV}\le \sqrt{s} \le 8$$
