Figure 3: The inelastic cross-section versus √s.
From: Measurement of the inelastic proton–proton cross-section at √s=7 TeV with the ATLAS detector
The ATLAS measurement for ξ>5×10−6 is shown as the red-filled circle and compared with the predictions of Schuler and Sjöstrand and Phojet for the same phase space. Data (filled circles for pp data and unfilled circles for pp̄ data) from several experiments are compared with the predictions of the pp inelastic cross-section from Schuler and Sjöstrand31 (as used by Pythia), by Block and Halzen15 and by Achilli et al.20 An extrapolation from the measured range of ξ>5×10−6 to the full inelastic cross-section using the acceptance of 87±10% is also shown (blue-filled triangle) based on the model by Donnachie and Landshoff for ɛ=0.085 for dσ/dξ. The experimental uncertainty is indicated by the error bar whereas the total (including the extrapolation uncertainty) is represented by the blue-shaded area.
