John Iliopoulos: New Physics at the LHC

John Iliopoulos

  • Yukawa's prediction of π meson
  • Luminosity
  • Atlas experiment
  • Vertex detector
  • NNLO (Next-to-next leading order) QCD


  • Perturbation theory is remarkably reliable.
  • Perturbation theory breaks down only when strong interactions become important. But new strong interactions imply new physics.
  • A light Higgs is found.
  • The Standard Model is complete.
  • Large extra dimensions.
  • No light Higgs is found.
  • New strong interactions.
  • Little Higgs.
  • The Higgs boson is a pseudo-Goldstone boson of a new symmetry.
  • The absence of a light Higgs implies new physics.
  • But a light Higgs is unstable without new physics.
