  We study, within the statistical hadronization model, the influence of narrow
strangeness carrying baryon resonances (pentaquarks) on the understanding of
particle production in relativistic heavy ion collisions. There is a great
variation of expected yields as function of heavy ion collision energy due to
rapidly evolving chemical conditions at particle chemical freeze-out. At
relatively low collision energies, these new states lead to improvement of
statistical hadronization fits.
