Abstract (data abstract)
CERN-LHC. Measurement of the production ratios of prompt charged particles (protons, pions and kaons) produced in proton-proton collisions at centre-of-mass energies of 900 GeV and 7 Tev using data of total integrated luminosities of 0.3 nb-1 and 1.8 nb-1 respectively. The data for both like-particle and different-particle ratios for particles with momenta > 5 GeV are given for three PT ranges, <0.8, 0.8-1.2 and >1.2 GeV as a function of the charged particle pseudorapidity. Promptness is defined as originating from the primary interaction, either directly, or through the subsequent decay of a resonance.
