FCC 1 and FCC2 (1/4)

<!--HTML-->FCC 1 Introduction to FCC: Michael Benedikt Astract: The introduction lecture will summarize motivation, scope, planning and organization of the FCC Study. Following the 2013 update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Study has been launched by CERN, to design an energy frontier hadron collider (FCC-hh) in a new 80-100 km tunnel with a centre-of-mass energy of about 100 TeV, an order of magnitude beyond the LHC's, as a long-term goal. The FCC study also includes the design of a 90-350 GeV high-luminosity lepton collider (FCC-ee) installed in the same tunnel, serving as Higgs, top and Z factory, as a potential intermediate step, as well as an electron-proton collider option (FCC-he). The physics cases for such machines will be assessed and concepts for experiments will be developed in time for the next update of the European Strategy for Particle Physics by the end of 2018. The FCC Study is organized as a global collaboration. FCC 2 Abstract: FCC Physics - Challenges and Potentials: Christophe Grojean, Michelangelo Mangano The triumph of the Standard Model is paradoxical: his success in describing with higher and higher accuracy the fundamental blocks of matter is daily reinforced by the LHC and still it provides no answer to the big questions concerning the fundamental laws that have shaped the Universe as we know it. New colliders beyond the LHC will probe the structure of matter and space-time to tinier distances and with higher sensitivity to reveal new natural phenomena and establish new paradigms for a better understanding of Nature. In the short time since the Future Circular Collider concept emerged, many studies have already been performed to explore the vast array of measurements that the FCC will enable. These range from the most precise determinations of the properties of the Higgs boson and of electroweak and QCD interactions, to the direct search for new particles with masses up to several tens of TeV. We shall review some of the most significant results of these studies, and discuss their implications in view of the big questions that High Energy Physics faces today.
