The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton–proton scattering at √ s = 8 TeV in the squared four-momentum transfer range 0.2 GeV2 < |t| < 1.9 GeV2. This interval includes the structure with a diffractive minimum (“dip”) and a secondary maximum (“bump”) that has also been observed at all other LHC energies, where measurements were made. A detailed characterisation of this structure for √s = 8 TeV yields the positions, |t|dip = (0.521 ± 0.007) GeV2 and |t|bump = (0.695 ± 0.026) GeV2, as well as the cross-section values, dσ/dt|dip = (15.1 ± 2.5) μb/GeV2 and dσ/dt|bump = (29.7 ± 1.8) μb/GeV2, for the dip and the bump, respectively.
