Abstract

We complete the model-independent analysis of the scaling properties of the differential cross section of elastic proton-proton cross sections, including new TOTEM data published in 2022 at s=8\sqrt{s} = 8 TeV. We separate the signal and the background region with a new gating method. In the signal region, we find that the statistical significance of Odderon exchange from the combined 7.0 and 8.0 TeV pppp data of TOTEM and the 1.96 TeV ppˉp\bar{p} data of D0 is at least 7.32σ\sigma. In the background region, the scaling functions of elastic proton-proton data at 7 and 8 TeV and that of elastic proton-antiproton scattering data at 1.96 TeV agree with a statistical significance not larger than 1.93σ\sigma.
