Predictions of hadron abundances in pp collisions at the LHC.

Based on the statistical hadronizationmodel, we obtain quantitative predictions for the relative abundances of hadron species in pp collisions at the LHC. By using the parameters of the model determined at √s = 200 GeV, and extrapolating the overall normalization from pp̄ collisions at the SPS and Tevatron, we find that the expected rapidity densities are almost grandcanonical. Therefore, at LHC the ratios between different species become essentially energy-independent, provided that the hadronization temperature TH and the strangeness suppression factor γS retain the stable values observed in the presently explored range of pp and pp̄ collisions.
