Abstract

The inclusive production of V0-particles, i.e. K0s mesons, Lambda and anti-Lambda baryons in ppcollisions at a centre-of-mass energy of 7 TeV is analyzed with the LHCb detector. The study is done separately for both polarities of the LHCb spectrometer magnet. The results are combined for the final cross-section measurements. The total luminosity used for the analysis is 1.8 nb−1. The production cross-section ismeasured in bins of the V0 phase space. The kinematic variables used are the V0 transverse momentum pT and rapidity y. The selected range for the kinematic variables is 0 <= pT <= 2.4 GeV/c and 2.5 <= y <= 4.5 for the K0s and 0.2 <= pT <= 2.4 GeV/c and 2.5 <= y <= 4.0 for Lambda and anti-Lambda. The measurements are compared with predictions from QCD based models of multi-hadron production at high energies.
