Description
We investigate, using the newest LHC data, the energy
dependence of hadron production within the framework of the
statistical hadronization model. The data are confronted with
predictions based on extrapolation from lower (RHIC) energies. While
the yields of hadrons made from light (u,d,s) quarks generally exhibit
little change apart from the overall increase in
multiplicity, a characteristic energy dependence is observed for J/psi
production. This feature is well described by statistical generation
of J/$\psi$ mesons at the phase boundary, as predicted in [1,2].
We also search for possible deviations from the statistical picture
in the yields of (anti-)baryons and light (anti-)nuclei.
