Takeda Lab (ICRR Cosmic Neutrino Division)
Machine-translated · View original
The lab seeks to uncover the birth and evolution of the universe through neutrinos and dark matter.
AboutAbout the lab
Reading the history of the universe through microscopic particles
Using neutrinos and dark matter as clues, the Takeda Lab studies how the universe was born and has evolved from the perspective of elementary particle physics.
Neutrinos are elementary particles that are all around us yet hard to notice, while dark matter is an unidentified particle completely different from the ordinary matter we see every day.
The lab is advancing the Hyper-Kamiokande project, a further evolution of Super-Kamiokande, and builds the detectors with its own hands.
The lab also promotes a direct dark matter search experiment being carried out in Italy.
Key terms
- Neutrino
- An elementary particle that carries no electric charge and hardly interacts with other matter. It is produced in huge numbers inside stars and in supernova explosions.
- Dark matter
- Unidentified matter that cannot be seen with light, but is thought to exist in large amounts in the universe based on its gravitational effects.
- Water Cherenkov detector
- A device that observes particles by detecting the bluish-white light (Cherenkov light) emitted when a charged particle travels through a large volume of water.
ResearchResearch themes
The lab aims to clarify how the universe was born and how it has evolved, from the perspective of elementary particle physics, which probes the microscopic world. Neutrinos and dark matter are its clues.
*Illustrative imageExploring Matter and the Evolution of the Universe with Neutrinos
The lab investigates why the universe is made of matter with almost no antimatter, by studying the properties of neutrinos. It also studies how matter has evolved in the universe, using neutrinos emitted by supernova explosions.
*Illustrative imageBuilding Hyper-Kamiokande
The lab is advancing the Hyper-Kamiokande project, a further evolution of Super-Kamiokande. With its own hands, it is building the world's largest water Cherenkov detector with controlled water quality.
*Illustrative imageDirect Detection of Dark Matter and Supernova Neutrinos
The lab aims at direct detection of dark matter in a search experiment underway in Italy, which has the highest sensitivity in the world. It also conducts research to deepen the understanding of how supernovae explode, by observing all types of neutrinos when a supernova explosion occurs near our galaxy.
