“Particle, Nuclear, and Astro Physics Simulation Program” is to promote theoretical studies on particle physics, nuclear physics, and astrophysics through large-scale numerical simulations. This program is based on “Large Scale Simulation Program” previously carried out in KEK.
With the progress of simulation studies in the fields of fundamental science, theoretical calculations directly connected to large-scale experimental and observational researches have now been available. The precise theoretical predictions to the experimental data are indispensable for maximizing the outcome of large-scale experiments carried out in KEK and other institutes over the world. These theoretical calculations involve large-scale computations, and thus it is important to promote simulation studies that are closely related to the progress of the experimental projects. Since many of recent large experiments are carried out under the international cooperation, it is also necessary to advance international collaboration in the theoretical researches.
In this program, we promote theoretical researches and international collaborations that tightly bind the areas of particle physics, nuclear physics and astrophysics and closely connected to experiments and observations. This program is supported by the prioritized distribution of grant (starting FY2018) and managed under the cooperation of Joint Institute of Computational Fundamental Science (JICFuS),
