Description
The discovery of the Higgs boson by the ATLAS and CMS experiments at CERN in 2012 revolutionised our understanding of the origin of matter and interactions in the universe. The proof of the existence of a scalar field supports the hypothesis of a spontaneous electroweak symmetry breaking mechanism responsible for the appearance of the mass of the Z0 and W± vector bosons in the very early moments. The discovery by ATLAS and CMS in 2015 of the existence of Yukawa couplings between elementary fermions and the Higgs field highlighted the importance of the “substance” of the vacuum for the story of our universe. Old questions are being exacerbated and new questions are emerging that could offer opportunities for discoveries at large colliders, in conjunction with cosmological observations, in the coming decades.
