LHC optics and elastic scattering measured by the TOTEM experiment
Abstract
The TOTEM experiment at the LHC has measured proton-proton elastic scattering in dedicated runs at s=7 and 8 TeV centre-of-mass LHC energies. The proton-proton total cross-section σ tot has been derived for both energies using a luminosity independent method. TOTEM has excluded a purely exponential differential cross-section for elastic proton-proton scattering with significance greater than 7σ in the |t| range from 0.027 to 0.2 GeV2 at s=8 TeV.
