The lab studies astroparticle physics, aiming to directly detect dark matter with instruments in the laboratory.

AboutAbout the lab
Catching the unknown matter that fills the universe, in the laboratory
The lab conducts experimental research in astroparticle physics.
Astronomical observations have shown that most of the matter filling the universe is an unknown substance called dark matter.
To uncover its true nature, the lab is working to directly capture the moment dark matter interacts in a detector in the laboratory.
The lab also studies neutrinos and proton decay, and is building Hyper-Kamiokande.
Key terms
- Dark matter
- Unknown matter that cannot be seen with light, but is known from its gravitational effects to exist in large amounts in the universe
- Neutrino
- An elementary particle that carries no electric charge and barely interacts with other matter, which makes it difficult to observe
- Proton decay
- A phenomenon in which the proton, thought to be stable, decays. It is predicted by grand unified theories but has not yet been observed

ResearchResearch themes
The lab aims to uncover the nature of dark matter, which makes up most of the matter filling the universe, and to open the door to the larger physical phenomena behind it. It also treats the study of neutrinos and proton decay as a major research theme.
*Illustrative imageDirect Detection of Dark Matter
This research aims to directly capture the moment dark matter interacts in a detector placed in the laboratory. The lab participates in the international research collaboration for the XENON experiment, which is under way in Italy, and aims to make a discovery with the world's highest sensitivity.
*Illustrative imageNeutrinos and Proton Decay
Building on its experience with Super-Kamiokande, the lab is building Hyper-Kamiokande, a far larger detector. By starting observations, it hopes to come closer to answering why matter exists in the universe at all.
