Abstract (data abstract)
CERN-LHC. Measurement of the inelastic proton-proton cross section at a centre-of-mass energy of 7 TeV. The data set has a total integrated luminosity of 20 mub-1 collected during a single 8 hour fill of the LHC beginning March 31st 2010. Scintillation counters in the forward region were used to select inelastic events. Results are given for a cut off of M(X)**2/S > 5*10**-6, equivalent to MX > 15.7 GeV at 7 TeV and also extrapolated to the full range M(P)**2/.S Note added 12/2/2014: The cross section values reported in the tables should be multiplied by factor 1.0187 to take into account the updated value of the integrated luminosity for ATLAS 2010 data taking period. The uncertainty on the global normalisation ('Lumi') increases slightly from 3.4% to 3.5%.See Eur.Phys.J. C73 (2013) 2518 for more detail.
