The original 2002/2003 CERN-mandated safety study for LHC heavy-ion running (predates and is superseded/extended by the 2008 LSAG report for the full pp programme). Considers negatively-charged strangelets, gravitational (micro) black holes, and magnetic monopoles as the theoretically envisaged dangerous objects; concludes no basis for concern, leaning heavily on cosmic-ray-survival arguments and, for micro black holes, on Hawking evaporation. Explicitly revisits the RHIC-era Busza/Jaffe/Sandweiss/Wilczek and Dar/De Rújula/Heinz analyses in light of then-current theory (including TeV-scale gravity / extra-dimension scenarios). relevance_note: the direct institutional predecessor of the LSAG report; establishes the argument template (cosmic-ray bound, Hawking evaporation) that LSAG later reuses and extends.
