Independent, contemporaneous derivation (arXiv:hep-ph/0106219) of TeV-scale collider black-hole production and Hawking decay, framed as “the end of short-distance physics” — argues geometric black-hole formation would replace conventional short-distance particle collisions above the true Planck scale, giving characteristic high-multiplicity thermal final states (~5:1 hadronic:leptonic). Co-canonical with Dimopoulos-Landsberg; both are the load-bearing production+decay calculation the LSAG report cites for Premise A. relevance_note: co-canonical primary for the production-cross-section/Hawking-decay premise; independently derived from Dimopoulos-Landsberg, strengthening the theoretical consensus the safety case leans on.
