The discovery in 2012 of the Higgs boson, the last ingredient of the standard model and responsible for the mass of elementary particles, is undoubtedly one of the most important discoveries in particle physics. It not only represents a theoretical and experimental milestone reached after 50 years of intense searching, requiring the design and construction of the LHC, the largest scientific and technological project of all time. The Higgs boson is a particle like no other in the standard model, the detailed study of which we hope will allow us to answer some of the most pressing questions about how nature works at its most fundamental level.
Over the last decade, the precision achieved at the LHC in the measurement of standard model processes, including the Higgs boson, as well as the ambition and creativity in the direct search for new physics, are enabling breakthroughs and perhaps the first cracks in the gleaming edifice of the standard model are already visible. With two decades of operation ahead of it, the LHC has not yet said its last word and revolutionary new discoveries may be awaiting.
However, despite its potential, the LHC has its limitations. In order to further penetrate the mysteries of the universe, new accelerators, capable of unprecedented precision and energy, are being designed.
