Measurement of proton-proton inelastic scattering cross-section at $\sqrt{s}$= 7 TeV
The TOTEM experiment at the LHC has measured the inelastic proton-proton cross-section at $\sqrt{s}$ = 7 TeV in a β* = 90 m run with low inelastic pile-up. The measurement was based on events with at least one charged particle in the T2 telescope acceptance of 5.3 < |η| < 6.5 in pseudorapidity...

| description | The TOTEM experiment at the LHC has measured the inelastic proton-proton cross-section at $\sqrt{s}$ = 7 TeV in a β* = 90 m run with low inelastic pile-up. The measurement was based on events with at least one charged particle in the T2 telescope acceptance of 5.3 < |η| < 6.5 in pseudorapidity. Combined with data from the T1 telescope, covering 3.1 < |η| < 4.7, the cross-section for inelastic events with at least one |η| < 6.5 final state particle was determined to be 70.5 2.9 mb. Based on models for low mass diffraction, the total inelastic cross-section was deduced to be 73.7 3.4 mb. An upper limit of 6.31 mb at 95 % confidence level on the cross-section for events with diffractive masses below 3.4 GeV was obtained from the difference between the overall inelastic cross-section obtained by TOTEM using elastic scattering and the cross-section for inelastic events with at least one |η| < 6.5 final state particle. |
