Where is the New Physics ? Main questions in today’s particle physics (a non-exhaustive list ..) Why is the Higgs boson so light (so-called “naturalness” or “hierarchy” problem) ? What is the origin of the matter-antimatter asymmetry in the Universe ? Why 3 fermion families ? Why do neutral leptons, charged leptons and quarks behave differently ? What is the origin of neutrino masses and oscillations ? What is the composition of dark matter (23% of the Universe) ? What is the cause of the Universe’s accelerated expansion (today: dark energy ? primordial: inflation ?) Why is Gravity so weak ? However: there is NO direct evidence for new particles (yet…) from the LHC or other facilities Where is the New Physics ? i.e. at what E scale(s) will we find the answers to these questions ?

Scientific strategy These questions require NEW PHYSICS With the discovery of the Higgs boson, we have completed the Standard Model (> 50 years of theoretical and experimental efforts !) Note: fermions (c, b, t, τ) discovered at accelerators in the US, bosons (g, W, Z, H) in Europe ! We have tested the Standard Model with very high precision (wealth of measurements since early ‘60s, in particular at accelerators) it works BEAUTIFULLY (puzzling …) no significant deviations observed (but difficult to accommodate non-zero neutrino masses) However: the SM is not a complete theory of particle physics, as several outstanding questions remain (raised also by precise experimental observations) that cannot be explained within the SM. These questions require NEW PHYSICS

Future Circular Colliders (FCC) International Collaboration: ~ 70 Institutes International conceptual design study of a ~100 km ring: pp collider (FCC-hh): ultimate goal  defines infrastructure requirements √s ~ 100 TeV, L~2x1035; 4 IP, ~20 ab-1/expt e+e- collider (FCC-ee): possible first step √s = 90-350 GeV, L~200-2 x 1034; 2 IP pe collider (FCC-he): option √s ~ 3.5 TeV, L~1034 Also part of the study: HE-LHC: FCC-hh dipole technology (~16 T) in LHC tunnel  √s ~ 30 TeV GOAL: CDR in time for next ES Machine studies are site-neutral. However, FCC at CERN would greatly benefit from existing laboratory infrastructure and accelerator complex 90-100 km ring fits geology

FCC FCC-hh: a ~100 TeV pp collider is expected to: explore directly the 10-50 TeV E-scale conclusive exploration of EWSB dynamics say the final word about heavy WIMP dark matter FCC-ee: 90-350 GeV measure many Higgs couplings to few permill indirect sensitivity to E-scale up to O(100 TeV) by improving by ~20-200 times the precision of EW parameters measurements, ΔMW < 1 MeV, Δmtop ~ 10 MeV The two machines are complementary and synergetic Many huge technological, design and operational challenges: e.g. ~16 T Nb3Sn magnets Demonstrator (16 T, 50 mm gap) ~ 1m, end 2018, 1980 1985 1990 1995 2000 2005 2010 2015 2020 2025 2030 2035 Physics Construction Proto Design FCC LHC HL-LHC 1/28/16
