We study the scaling properties of the differential cross section of elastic proton–proton (pp) and proton–antiproton () collisions at high energies. We introduce a new scaling function, that scales – within the experimental errors – all the ISR data on elastic pp scattering from –62.5 GeV to the same universal curve. We explore the scaling properties of the differential cross-sections of the elastic pp and collisions in a limited TeV energy range. Rescaling the TOTEM pp data from TeV to 2.76 and 1.96 TeV, and comparing it to D0 data at 1.96 TeV, our results provide an evidence for a t-channel Odderon exchange at TeV energies, with a significance of at least 6.26. 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 TeV, with a range gradually narrowing with decreasing colliding energies.
