ATLAS is an international collaborative experiment which consists of about 3,000 researchers from more than 177 institutes in 38 countries. ATLAS discovered the Higgs boson in 2012. Nagoya team led by Prof. Tomoto plays a leading role in searching for the new particles, such as supersymmetric particles and measuring properties of the Higgs boson, as well as developing/constructing/operating electronics and software of "muon trigger system" which makes a decision whether an event caused by a proton-proton collision contains muons from the decays of Higgs bosons and new particles.
The Belle II experiment at the SuperKEKB accelerator in Japan aims to solve the great mysteries of particle physics.The Belle II collaboration consists of over 500 physicists and engineers from 97 institutions in 23 countries. The team at Nagoya University led by Prof. Iijima is one of the major research groups in the Belle II collaboration, which plays leading roles in various aspects of the project: construction and operation of a particle detector, called "TOP counter", newly developed by the Nagoya team, development of data processing methods using the high performance computers at KMI, and data analysis to find new phenomena.
space gravitational-wave antenna with a frequency band between 0.1 and
10 Hz. DECIGO consists of three spacecraft 1,000 km apart with laser
interferometers. The most important objective of DECIGO is the detection
of primordial gravitational waves to reveal the secret of the beginning
of the Universe. Other science targets include direct measurement of the
acceleration of the Universe, the revelation of the formation of massive
black holes, and many others. As a pathfinder science mission of DECIGO,
we plan to launch B-DECIGO in 2034. Nagoya University (KMI) is one of
the leading institutes for DECIGO.

Super-Kamokande is a water Cherenkov detector with 50 kton of ultra-pure water located at 1000 m underground of the Kamioka mine.
We study property of neutrinos by using various neutrino sources such as the sun, cosmic-rays, and the accelerator.
We are also conducting neutrino astrophysics and searching for proton decays.
The water will be enchanted with Gd doping in order to detect neutrinos from past super-novae.
KMI contributes to atmospheric neutrino oscillations and dark matter search using neutrinos.
