Abstract The dependence of the rate of proton–proton interactions on the centre-of-mass collision energy,√ s, is of fundamental importance for both hadron collider physics and particle astrophysics. The dependence cannot yet be calculated from first principles; therefore, experimental measurements are needed. Here we present the first measurement of the inelastic proton–proton interaction cross-section at a centre-of-mass energy,√ s, of 7 TeV using the ATLAS detector at the Large Hadron Collider. Events are selected by ...
