Abstract: (Springer)

We study the scaling properties of the differential cross section of elastic proton–proton (pp) and proton–antiproton (

p\bar{p}

) 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

\sqrt{s} = 23.5

–62.5 GeV to the same universal curve. We explore the scaling properties of the differential cross-sections of the elastic pp and

p\bar{p}

collisions in a limited TeV energy range. Rescaling the TOTEM pp data from

\sqrt{s} = 7

TeV to 2.76 and 1.96 TeV, and comparing it to D0

p\bar{p}

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

\sigma

. 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

TeV, with a

-t

range gradually narrowing with decreasing colliding energies.
