11 LHC = Black Hole Factory?
BH X LHC = Black Hole Factory? Problem: No fundamental scattering operator for |A> + |B> --> BH + X Model for cross section: impact parameter b Parton model- fold structure fct.: 20/11/2018 Horst Stöcker, FIAS & ITP, J.W. Goethe- Universität Frankfurt am Main

Production probabilities significantly increased for Pb+Pb Ncoll=200! 1000 times! Landsberg & Giddins: LXD-BHs Production Nanobarn In ! Pb+Pb Microbarn!! * ** * Bleicher, Hofmann, Hossenfelder, Stoecker Phys.Lett. B548:73-76,2002 ** Hossenfelder: Phys.Lett.B598:82-98,2004 20/11/2018 Horst Stöcker, FIAS & ITP, J.W.

13 High pT Di-Jet -Suppression at LHC:
Di- Jets with M> Mf vanish behind Schwarzschild radius Rh High pT ~ Mf sppression in AB -> Jet(pT)+X => #Jet(pT) << #Jet(pT) in LXDs in D=4 => 1/pt physics: hidden behind horizon! LHC - where are my Di-Jets gone? 20/11/2018 Horst Stöcker, FIAS & ITP, J.W. Goethe- Universität Frankfurt am Main

14 Hard Scattering: NO Di-Jets, but BHs !
