SPC Report on LSAG Documents

The CERN Scientific Policy Committee (SPC) was asked by the President of the CERN Council to examine the documents produced by the LHC Safety Assessment Group (LSAG) and to provide Council with an independent opinion on the conclusions stated in those documents. A dedicated SPC panel was set up, composed of Peter Braun-Munzinger, Matteo Cavalli-Sforza, Gerard ‘t Hooft, Bryan Webber and Fabio Zwirner. The documents made available to the panel were: "Review of the Safety of LHC Collisions", by the LHC Safety Assessment Group (LSAG report); "Astronomical Implications of Hypothetical Stable TeV-Scale Black Holes", by S.B.Giddings and M.L.Mangano (GM paper). After thorough review, discussion and ensuing endorsement by the full SPC, the requested opinion is summarized in the present document.
