Purpose and significance

Elucidating the ultimate laws of physics at a microscopic level will lead to an understanding of the beginning of the universe. The discovery of the Higgs boson confirmed the Standard Model of particle physics below a certain energy scale, ~ tera electron volts (TeV). The Standard Model is however incomplete as an ultimate law, as it does not contain the dark matter in it.
We plan to perform large-scale simulations of lattice quantum chromodynamics (QCD) in order to calculate the physical quantities needed to interpret the experimental results obtained at large particle accelerators such as SuperKEKB and J-PARC.
By precisely testing the Standard Model, we aim to find indications of a more fundamental theory behind it. This project also focuses on a study of the phase transition occurred in the early universe and a numerical study of superstring theory.

Future outlook: 10 years later and beyond

• We will be able to precisely determine the hadronic form factors needed to analyze the data from SuperKEKB.
• We will be able to quantitatively elucidate the phase transition that occurred in the process of the Big Bang.
• We will be able to precisely verify the gauge/gravity correspondence, which is an important prediction of superstring theory.
• We will establish an efficient methodology that incorporates the effects of quantum electrodynamics (QED), so that we can calculate the density fluctuations in the early universe, for direct comparison with observational data for cosmic background radiation.
