Abstract : The cross-section for inelastic proton-proton collisions, with at least one prompt long-lived charged particle of transverse momentum pT>0.2 GeV/c in the pseudorapidity range 2.0<η<4.5, is measured by the LHCb experiment at a centre-of-mass energy of s√=7 TeV. The cross-section in this kinematic range is determined to be σaccinel=55.0±2.4 mb within the spectrometer acceptance with an experimental uncertainty that is dominated by systematic contributions. Extrapolation to the full phase space, using PYTHIA 6, yields σinel=66.9±2.9±4.4 mb, where the first uncertainty is experimental and the second is due to the extrapolation.
