Large Hadron Collider

Definition

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator, located at CERN near Geneva, Switzerland. It accelerates protons and heavy ions to nearly the speed of light before colliding them, allowing scientists to study fundamental particles and the forces that govern their interactions. This facility has been instrumental in the search for dark matter particle candidates, shedding light on potential particles that could make up dark matter, a mysterious substance that constitutes a significant portion of the universe's mass-energy content.

5 Must Know Facts For Your Next Test

1. The LHC consists of a 27-kilometer ring of superconducting magnets and detectors that collide particles at unprecedented energy levels, reaching up to 13 TeV in collisions.
2. The facility has played a crucial role in confirming the existence of the Higgs boson, which was a major milestone in particle physics and helped solidify the Standard Model.
3. Research at the LHC is not only focused on the Higgs boson but also on searching for evidence of new particles that could account for dark matter candidates like WIMPs (Weakly Interacting Massive Particles).
4. The LHC's experiments are designed to explore conditions similar to those just after the Big Bang, providing insights into the early universe and fundamental physics.
5. As scientists analyze data from billions of particle collisions, they hope to uncover hints about physics beyond the Standard Model, including potential dark matter candidates.
