From: Evidence of Odderon-exchange from scaling properties of elastic scattering at TeV energies
Left panel: Scaling function \(H(x) = \frac{1}{B \sigma _\mathrm{el} }\frac{d\sigma }{dt}\) of the differential cross section of elastic pp collisions at \(\sqrt{s} = 2.76\) TeV LHC (red), as compared to that of the elastic \(p\overline{p}\) collisions at the Tevatron energy of \(\sqrt{s} = 1.96\) TeV (blue), shown as a function of \(x = -tB\). Right panel: Same as the left panel, but now using elastic pp data at \(\sqrt{s} = 7\) TeV (red), as compared to elastic \(p\overline{p}\) collisions at \(\sqrt{s} = 1.96\) TeV (blue). On both panels, statistical errors and t-dependent systematic errors are added in quadrature. Lines are shown to guide the eye, corresponding to fits with the model-independent Lévy series from Refs. [9, 26]
