Harry Cliff: Particle Physics and the Large Hadron Collider
Core Takeaways
The Large Hadron Collider (LHC) accelerates particles to 99.9999991% of light speed using powerful magnets in a 27 km tunnel.
Why it matters
This speed allows the LHC to probe fundamental forces and particles, crucial for testing the Standard Model.
Particles are ripples in quantum fields, not fundamental units, with the Higgs boson discovered via LHC proton collisions.
▶ 5:00
Why it matters
This challenges the traditional view of particles, reshaping our understanding of mass and fundamental forces.
The Future Circular Collider is planned to be 100 km in circumference, costing about 30 billion euros, targeting completion by 2070.
▶ 1:15:00
Why it matters
This ambitious project aims to push the boundaries of particle physics, potentially uncovering new physics beyond the LHC.
B quarks oscillate between matter and antimatter, providing insights into why the universe is predominantly matter.
▶ 45:00
Why it matters
Understanding this asymmetry could explain the matter-dominated universe, a major question in cosmology.
Supersymmetry, a theory predicting super partners for particles, remains unproven after a decade of LHC data.
▶ 1:25:00
Why it matters
The lack of evidence challenges a key theoretical framework that could stabilize the Higgs field without fine-tuning.
