An independent (non-CERN-commissioned) technical paper published within weeks of the LSAG report, addressing the specific “dangerous chain reaction” concern (that a mini black hole could grow by accreting surrounding matter rather than evaporating). Argues systematically, via Hawking-radiation and accretion-rate calculations, that any LHC-produced black hole’s accretion timescale is vastly longer than its evaporation timescale, so runaway growth cannot occur; folds in new arguments (e.g. the effect of black hole mass growth on accretion rate) beyond what was in the RHIC-era and CERN-2003-001 reports. relevance_note: an independent, non-institutional check on the specific micro-black-hole growth mechanism, published in parallel with LSAG rather than derived from it — bears on whether the safety verdict is corroborated outside the official-report chain.
