AboutAbout the lab
Searching for new physics in the differences between particles and antiparticles
Higuchi Lab (Kavli IPMU Belle II Experiment Group) takes part in the Belle II high-energy accelerator experiment, aiming to discover new elementary particle physics and build a framework for it.
Belle II is an experiment at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Ibaraki Prefecture, in which electrons and positrons are collided.
The lab records in detail the behavior of the B mesons and other particles produced, and examines whether there are any discrepancies with the predictions of the Standard Model of particle physics.
The lab also works on operating the silicon vertex detector, which measures the positions of particles, and on developing new detectors.
Key terms
- Standard Model of particle physics
- A theory that summarizes the elementary particles discovered so far and how the forces acting between them work
- B meson
- A particle containing a b quark. Some of the reactions it takes part in are thought to be particularly sensitive to the effects of new elementary particle theories
- CP violation
- A difference in properties between particles and antiparticles

ResearchResearch themes
The lab searches for new elementary particle physics, using facts that the Standard Model of particle physics cannot explain, such as dark matter and neutrino masses, as clues. Through the Belle II experiment, it precisely examines the behavior of B mesons and other particles, looking for discrepancies with the predictions of the Standard Model.
*Illustrative imageThe Belle II Experiment
The Belle II experiment at KEK collides electrons and positrons to produce particles such as B mesons, D mesons, and tau leptons, and records their behavior in detail. The lab searches for discrepancies with the Standard Model together with researchers and students from Japan and around the world.
*Illustrative imageSilicon Vertex Detector (SVD)
In collaboration with institutions in Japan and abroad, the lab developed and mass-produced the sensor modules of the silicon vertex detector, which measures particle positions in Belle II. Building on that technology, it works on keeping the SVD running stably and on developing new particle position detectors.
*Illustrative imagePrecision Measurement of CP Violation
In a variety of reactions involving B mesons, the lab precisely measures the differences in properties between particles and antiparticles (CP violation) and compares them with the predictions of the Standard Model, seeking evidence for new elementary particle theory. Knowledge gained from the SVD is applied to this research.
