summary - The first LHC-specific safety report (“LHC Safety Study Group”), predecessor to the 2008 LSAG review. Assesses strangelets, black holes, magnetic monopoles and vacuum-stability transitions in heavy-ion collisions at the LHC, concluding “no basis for any conceivable threat” (INSPIRE records only 3 citing papers as of this read - likely an undercount, since as a CERN Yellow Report never posted to arXiv it is often cited via its CDS record number or superseded by direct references to LSAG instead). It predates the 2001-02 TeV-scale black-hole production proposals (Dimopoulos-Landsberg, Giddings-Thomas) and the later stable-black-hole/astrophysical-bound refinement, so its black-hole discussion is largely superseded by LSAG’s 2008 update.
relevance_note - Shows the official argument’s pre-2008 state and establishes the cosmic-ray-survival template LSAG later extends to TeV-gravity black holes.
