Description
The TOTEM experiment at the LHC has measured proton-proton elastic scattering in dedicated runs at \sqrt{s}=7 and 8 TeV centre-of-mass LHC energies. The proton-proton total cross-section \sigma_{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 7\sigma in the |t| range from 0.027 to 0.2 GeV^{2} at \sqrt{s}=8 TeV. The TOTEM experiment measured elastic scattering at \sqrt{s}=8 TeV in the Coulomb-Nuclear Interference Region. TOTEM has also measured diffractive scattering at \sqrt{s}=7 and 8 TeV in different event topologies.
