The Higgs boson has been found : what next ?

Orateur : Prof. Johann COLLOT (LPSC, Université Grenoble-Alpes, CNRS/IN2P3, Grenoble)

Undeniably, the discovery of the Higgs boson that was announced at CERN on 4 July 2012, will be remembered as one of the major scientific triumphs of the XXIst century. All in all, it took 50 years, more than 10000 physicists, three major projects : LEP, TeVatron and LHC - and 10 billion € of investment to confirm the existence of this new fundamental particle. In the first part of the colloquium, the audience will be remembered the reasons that deeply motivated this global endeavor ; how the fundamental description of the basic constituents of nature and their interactions calls for the existence of a new field : the Higgs field and its associated boson. The presentation will then move to the LHC program and the discovery of the Higgs boson, indeed. The colloquium will conclude on the present global plans to try solve the next big puzzle of contemporary physics : what is the microscopic nature of dark matter ?
