The ATLAS experiment aims to discover new physics phenomena, using world highest energy proton-proton collider called Large Hadron Collider (LHC) at CERN located in the vicinity of Geneva, Switzerland.
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.
The FORCE mission aims to cover wide X-ray energy band of 1-80 keV, with good angular resolution of ~10'' and inprecedented sensitivity above 10 keV, the hard X-ray energy band. The mission is based on the heritage of Hitomi satellite hard X-ray imager, which showed the best hard X-ray sensitivity as then. With 10 times sharper X-ray mirror uner development with NASA team, FORCE provides an order of magnitude better sensitivity. Nagoya University contributes to mirror development and calibration, satellite system concept design, and detector design.
NOP experiment is a project for fundamental physics with slow neutrons; for example, precision measurement of neutron lifetime, search for new physics through P- and T-violation, and search for extra-dimension and dark energy. The main site of the project is J-PARC, which is the world-highest intense spallation neutron source. Furthermore, accelerator-driven neutron sources and research reactors both inside and outside of Japan are also utilized. Nagoya team has critical roles in a number of aspects in the project: R&D of various devices for neutrons, designing the experiments, measurements, and analysis.
An X-ray observatory is to be launched on 2022, lead by JAXA/ISAS. The mission is capable of X-ray spectroscopy with a resolving-power 30 times better than the existing X-ray missions. From this mission we can expect to observe the dynamical status of hot plasmas in high-energy sources, such as clusters of galaxies and black holes, with unprecedented accuracy. Also, the mission is a powerful tool to diagnose the ionization states of metals around high-energy sources, and searching for minor metals in such objects. Nagoya University contributes to the spectrometer and science operations team.
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.
Hyper-Kamiokande is a next generation neutrino detector with 190 kton of water Cherenkov detector, having 8-times larger fiducial volume. Thanks to its large mass of Hyper-Kamiokande, we hope to discover neutrino CP violation, recently hinted by T2K long-baseline neutrino oscillation experiments, as well as to detect proton decays, which could be the evidence of Grand Unified Theory. Aiming to start its operation in 2027, KMI is contributing toR&D works for newly developed optical sensors, and new neutrino astrophysics with MeV-GeV energies.
