Ultracold Neutrons and the Matter-Antimatter Mystery | Canada 🇨🇦

Canada Connect: Coffee Talk with an Early Career Researcher

At TRIUMF, Canada’s particle accelerator centre, we use ultracold neutrons to tackle one of physics’ biggest open questions: Why does our Universe contain matter? If the Big Bang created equal amounts of matter and antimatter, they should have annihilated. With collaborators in Japan, Mexico and the US, we built the world’s most intense ultracold-neutron source at TRIUMF to search for tiny effects behind this imbalance. Quantum sensors provide the magnetic-field control this search requires.
