Predictions of hadron abundances in pp collisions at the LHC

TL;DR

This paper uses the statistical hadronization model to predict hadron abundances in proton-proton collisions at the LHC, suggesting energy-independent ratios under certain conditions, based on extrapolated parameters from previous experiments.

Contribution

It extends the statistical hadronization model to LHC energies, providing quantitative predictions for hadron ratios in pp collisions using extrapolated parameters.

Findings

Predicted hadron ratios are nearly energy-independent at LHC.

Expected rapidity densities are almost grand-canonical.

Hadronization temperature and strangeness suppression factor remain stable.

Abstract

Based on the statistical hadronization model, 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 sqrt s = 200 GeV, and extrapolating the overall normalization from ppbar collisions at the SPS and Tevatron, we find that the expected rapidity densities are almost grand-canonical. Therefore, at LHC the ratios between different species become essentially energy-independent, provided that the hadronization temperature T_H and the strangeness suppression factor gamma_S retain the stable values observed in the presently explored range of pp and ppbar collisions.
