Measurement of the total cross section from elastic scattering in pp collisions at s = 7 TeV with the ATLAS detector
Original language description
A measurement of the total pp cross section at the LHC at s=7 TeV is presented. In a special run with high- ?* beam optics, an integrated luminosity of 80 ?b 1 was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t . The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the |t| range from 0.01 GeV2 to 0.1 GeV2 to extrapolate to |t|0 , the total cross section, ?tot(ppX) , is measured via the optical theorem to be: ?tot(ppX)=95.350.38(stat.)1.25(exp.)0.37(extr.)mb, where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertaintiesin the extrapolation to |t|0 .
