Implications of LHC heavy ion data for multi-strange baryon production

Key Points

This research aims to understand heavy ion collisions and their implications for strangelet production.
Analyzed data from LHC operations to evaluate baryon production estimates.
Compared findings with previous models from RHIC and other accelerators.
Assessed thermal production limits of normal and exotic nuclei.
LHC data sharpens previous estimates on baryon production limits.
Confirms that producing strangelets requires immense energy, beyond practical capabilities.
Suggests significant constraints on the existence of exotic quark matter.

Abstract

Prior to the start of LHC operations, the good agreement of measurements of particle production at RHIC and other accelerators with simple thermodynamic models allowed one to constrain severely any production of hypothetical strangelets in heavy ion collisions at the LHC. In particular, the LHC Safety Assessment Group (LSAG) estimated that the thermal production of a single normal A = 10 nucleus in heavy ion collisions would require running the equivalent of 1000 LHCs for the entire lifetime of the Universe. This estimate of the production of normal nuclear matter provided an extremely conservative upper bound on the production of hypothetical exotic forms of strange quark matter. This argument has now been sharpened by LHC data.
