الوصف: Measurements of hadron production in pp collisions at sqrt(s) = 0.9, 2.36 and 7 TeV recorded with the CMS detector are reported. Transverse momentum, pseudorapidity and multiplicity distributions of charged hadrons are presented. For non-single-diffractive collisions, the average charged-hadron transverse momentum and pseudorapidity density reveal an increase in production rate not well matched by theory and models. Measured spectra of identified strange particles, K0S, Lambda, anti-Lambda, Xi- and Xi+, reconstructed based on their decay topology, are also presented. The production rates for strange particles are observed to be in excess of those predicted by Monte Carlo models by up to a factor of three.
