The Fields and Particles division of the "Societé Française de Physique" supports the CERN project for the future and encourages the study of an e+e- collider to measure the Higgs, top, Z and W properties in depth. Check the conclusions delivered after the "Journée: Futur de la Physique des particules", at LPNHE, Paris, and Patrick Janot's FCC talk in this context.
The FCC-ee in a few words
The FCC-ee, formerly known as TLEP, is a high-luminosity, high-precision e+e- circular collider envisioned in a new 80-100 km tunnel in the Geneva area. With a centre-of-mass energy from 90 to 400 GeV, the physics program could pave the way towards the discovery of physics beyond the Standard Model, casting light on unanswered questions, such as dark matter, the baryon asymmetry of the Universe, the hierarchy problem, the stability of the Universe or the nonzero neutrino masses.
