Oscillations in elastic scattering at large momentum transfer at the LHC?

Abstract

The available data on elastic scattering at the LHC at large momentum transfer $t$ in the range $0.05<|t|<1.0{\mathrm{GeV}}^2$ have been analyzed in terms of possible oscillating structures. A clearly significant structure is seen in the data from the TOTEM collaboration at 13 TeV. Data measured by the same collaboration at 2.76~TeV, 7~TeV and 8~TeV are not statistically significant to confirm or reject the observation at~13 TeV. More data are needed to understand if the effect is real or an experimental artefact
