A detector lab aiming to measure the Higgs boson with high precision at next-generation accelerators.

AboutAbout the lab
Building a Higgs factory, together with the world.
The Suehara Lab conducts experimental research in high-energy physics, searching for new physics beyond the Standard Model of particle physics.
Aiming to realize Higgs factories such as the ILC (International Linear Collider), the planned successor to the LHC, the lab advances research on both physics and detectors.
Using that detector technology, the lab also promotes experiments searching for axion-like particles with the accelerators of the High Energy Accelerator Research Organization (KEK).
The lab also pursues deep learning research for these experiments, in collaboration with partner institutions in Japan and abroad.
Key terms
- Higgs factory
- A next-generation accelerator that collides electrons and positrons and is specialized for measuring the Higgs boson precisely
- Calorimeter
- A type of detector used in particle physics experiments that measures the full energy of incoming particles
- Deep learning
- A machine learning method in which a neural network with many stacked layers learns features from large amounts of data

The lab carries out physics and detector research for future colliders aimed at realizing a Higgs factory, along with experiments searching for unknown particles that make use of that detector technology. It takes on this work as an international collaboration, joining forces with researchers around the world.
*Illustrative imageHiggs Factory
This is a next-generation large-scale project that uses a huge accelerator and ultra-high-precision detectors to measure the Higgs boson precisely, with sensitivity far exceeding that of the current LHC experiments. The lab works on physics analysis and detector development in cooperation with researchers around the world.
*Illustrative imageSearch for Unknown Particles
The lab searches for axion-like particles in EBES, a beam dump experiment using a high-intensity beam. Although it is a small-scale experiment, its appeal is that you can control many parts of the experiment yourself.
*Illustrative imageDeep Learning
Using state-of-the-art deep learning such as Transformers and graph neural networks, the lab develops methods to reconstruct physics events from detector data with higher accuracy.
*Illustrative imageCalorimeter Development
Higgs factories use imaging calorimeters that are finely segmented in three dimensions. The lab develops finely segmented calorimeters, including ones based on silicon pad sensors and ones that take advantage of dual-readout technology.
