The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton–proton scattering at 
in the squared four-momentum transfer range 
. 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 yields the positions, 
and 
, as well as the cross-section values, 
and 
, for the dip and the bump, respectively.
