Measurement of the total cross section from elastic scattering in $pp$ collisions at $\sqrt{s}=7$ TeV with the ATLAS detector

ATLAS Collaboration

A measurement of the total $pp$ cross section at the LHC at $\sqrt{s}=7$ TeV is presented. In a special run with high-${\beta }^{\star }$ beam optics, an integrated luminosity of 80 $\mu$b$^…
