| Description | The Long Term Vision of Particle Physics at CERN Seminar Type: Colloquium Speaker: Albert De Roeck Date/Time: Monday Apr 22, 2024 4:10pm-6:00pm Location: Roessler 55 & Zoom Description: CERN is the European Laboratory for Particle Physics in Europe, and hosts the largest particle collider in the world, the 27 km proton-proton Large Hadron Collider (LHC) producing collisions at a centre of mass energy of 13-14TeV. CERN was founded in 1954. At CERN the Higgs particle was detected in 2012. CERN is now strongly engaged in planning for the future, which includes the study and evaluation of a new particle collider, in a ring of 90 km: the Future Circular Collider FCC.\r\n\r\nThe first possible machine would be a new powerful electron-positron collider. Such a collider will be an exciting precision instrument with fantastic capabilities to study in detail properties of the Higgs particle, as well as of all other heavy fundamental particles we know to date, such as W and Z bosons and the top quark. We also expect to get further insight beyond the Standard Model, and hunt for candidates for dark matter.\r\n\r\nFollowing a very thorough mid-term review process of the feasibility study of the project end of 2023, the Future Circular Collider is starting to take more clearly a central stage in the next, long term, plans of CERN. In this lecture we will present the highlights of the physics case for the FCC, and the recent progress of the feasibility studies for the construction of such a new circular collider. The machine is envisaged to have two phases, starting with e+e- collisions up to 365 GeV and at a later stage with pp collisions close to 100 TeV. Estimated costs and possible timelines will be discussed.\r\n\r\nAt the same time, CERN plans in the next years also to construct a facility to search for the dark sector or the Universe with searches for dark photons, light dark matter candidates, axions and more. CERN has also a significant involvement in preparatory studies for a muon collider.\r\nOn 21 March 2024, the CERN Council decided to launch the process for updating the European Strategy for Particle Physics (ESPPU) — the European analogon to the P5 process in the US— with a view to concluding the process in June 2026. Hence there are exiting times ahead for setting a possible future of particle physics in the coming few years. |
