The road to excellence in understanding of the universe
More than 45 years ago, the theory of electroweak interaction of elementary particles was created, which then got a detailed experimental confirmation and the name of the Standard Model. The Higgs boson is the last building block of the Standard Model. Only to establish the fact of the existence of the boson, it was necessary to build a powerful proton accelerator — the Large Hadron Collider, the length of the tunnel of which is about 27 kilometers. This collider accelerates protons to a speed sufficient to produce the Higgs boson even if it would be as heavy as 800 neutrons. Previously, in experiments on the less powerful collider LEP, it was established that the mass of the Higgs boson certainly exceeds 120 neutron masses.
