Abstract

We study the scaling properties of the differential cross section of elastic proton–proton (pp) and proton–antiproton (pp¯) 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 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 pp¯ collisions in a limited TeV energy range. Rescaling the TOTEM pp data from s=7 TeV to 2.76 and 1.96 TeV, and comparing it to D0 pp¯ 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 6.26σ. We complete this work with a model-dependent... (More)

We study the scaling properties of the differential cross section of elastic proton–proton (pp) and proton–antiproton (pp¯) 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 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 pp¯ collisions in a limited TeV energy range. Rescaling the TOTEM pp data from s=7 TeV to 2.76 and 1.96 TeV, and comparing it to D0 pp¯ 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 6.26σ. 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 200GeV≤s≤8 TeV, with a - t range gradually narrowing with decreasing colliding energies.
