Measurement of proton-proton inelastic scattering cross-section at [radic]s = 7TeV

The TOTEM experiment at the LHC has measured the inelastic proton-proton crosssection at ... TeV in a ... 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 ... in pseudorapidity. Combined with data from the T1 t...

Zusammenfassung:	The TOTEM experiment at the LHC has measured the inelastic proton-proton crosssection at ... TeV in a ... 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 ... in pseudorapidity. Combined with data from the T1 telescope, covering ..., the cross-section for inelastic events with at least one ... final-state particle was determined to be ... mb. Based on models for low mass diffraction, the total inelastic cross-section was deduced to be ...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 ... final-state particle.(ProQuest: ... denotes formulae/symbols omitted.)
