Special Physics Colloquium

Abstract: The discovery of the Higgs boson completed the Standard model and particle physics enters a new era, in which new phenomena are required, but at unknown energy scale and coupling strength. This requires a broad program of searches. The broadest program is offered by the Future Circular Collider (FCC) project at CERN, with a ultimate goal of reaching > 100 TeV in pp collisions. The first step of this program is a circular e+e- collider, offering unprecedented levels or precision and sensitivity to feebly coupled particles. Bio: Alain Blondel is Professor emeritus from University of Geneva and guest professor at CERN. He is leading the effort of physics and experiments for the Future Circular Collider FCC-ee at CERN, a high luminosity e+ e- machine able to produce 5x1012 Z, 108 WW events, 2x106 ZH events and more than 106 top quark pairs. The proposals for the FCC were just submitted to the CERN European Strategy for Particle Physics, which hopefully will endorse the FCC 100km facility around CERN providing powerful means to search for answers to the big questions. He previously worked in the T2K experiment, preparing HyperK, towards neutrino CP violation. He has a long career since 1974, with the Gargamelle experiment and LEP as highlights, and was awarded a number of prizes for his creative work, in particular on the determination of the number of neutrinos and the prediction of the top quark mass from radiative corrections.
