What will this 100 km particle accelerator envisaged by CERN do?

The European Council for Nuclear Research has presented its new 20 billion euro project: a new gigantic particle accelerator that would serve as a Higgs boson plant, to find out more about this elementary particle.

When built, it will be the largest and most powerful particle accelerator in the world. Hank Pym will only have to behave well! The European Council for Nuclear Research (CERN) has announced its intention to build the Future Circular Collider (FCC), or future hadron collider (which designates subatomic particles like protons or neutrons). With a circumference of 100 kilometers, this huge circular tube would be used to generate kinetic energy of 100 tetraelectrons volts (TeV) in order to burst physical particles between them. Their collision would thus produce the Higgs bosons, discovered in 2012 by CERN itself, or even other still unknown elementary particles, for example relating to dark matter. For this, the scientific organization would need 23 billion dollars (about 20.3 billion euros), coming from the European countries members of the Council but also, very probably, from other countries like Japan or the United States. United.

Once funded, the FCC would be built under the city of Geneva, in Switzerland, from 2038. Then, when it is operational, it will serve primarily as a “Higgs factory”, by the collision of electrons and positrons , in order to produce this mysterious particle in large quantities. This will allow particle physicists to learn more about this element which they suspect is the keystone of the fundamental structure of matter. In a second step, the FCC should be able to burst protons together to possibly discover new particles. These new studies and possible discoveries will refine or challenge the Standard Model on which all of the knowledge in particle physics is based. “We know the only way to find answers is to experiment,” said Tara Shears, a physicist at the University of Liverpool, in a Nature article on the subject. But the only place to find these answers is where we haven’t been able to search yet. ”
