TOTEM has measured the differential cross-section for elastic proton-proton scattering at the LHC energy of √s = 7 TeV analysing data from runs with a standard β∗ = 1.5m optics. The differential cross section is measured over a |t|-range from 0.36 to 2.5GeV2. The differential cross-section shows a significant diffractive minimum at |t| = (0.53 ±0.01stat± 0.01syst) GeV2.

Abstract

TOTEM has measured the differential cross-section for elastic proton-proton scattering at the LHC energy of √s = 7 TeV analysing data from runs with a standard β∗ = 1.5m optics. The differential cross section is measured over a |t|-range from 0.36 to 2.5GeV2. The differential cross-section shows a significant diffractive minimum at |t| = (0.53 ±0.01stat± 0.01syst) GeV2. For |t |-values larger than ∼ 1.5GeV2, the cross-section exhibits a power law behaviour with an exponent of -7.8 ± 0.3stat ±0.1syst. The data are compared to predictions based on different available models and show a strong discriminative power.
