Abstract (data abstract)
CERN-LHC. Measurement of the elastic differential cross section in proton-proton interactions at a centre-of-mass energy of 7 TeV. The data, which cover the |t| range 0.005-0.2 GeV**2, were collected using Roman Pot detectors very close to the outgoing beam in October 2011, allowing the precise extrapolation down to the optical point, t=0, and hence the derivation of the elastic as well as the total cross section via the optical theorem. An earler publication (CERN-PH-EP-2011-101,EPL 95(2011)41001) reports measurements in the higher |t| range from 0.36-2.5 GeV**2.
