Colloquium: Christophe Grojean, DESY

With the discovery of the long sought-after Higgs boson at CERN in July 2012, a new state of matter and a new dynamical principle have been revealed as essential building blocks of the fundamental laws of physics.  It provides a solution to the half-century-old mass conundrum, i.e., the apparent incompatibility between the mass spectrum of the elementary particles and their fundamental interactions.   I shall describe the Higgs physics precision program that will guide new physics searches at the high-energy frontier at the next runs of the LHC itself and at other future facilities.
