Advancements in Dark Matter Research at UCLA by Katsushi Arisaka

The Dark Matter Programs at UCLA, led by Dr. Katsushi Arisaka from the Department of Physics and Astronomy, focus on both direct and indirect detection methods for dark matter. Key projects include XENON100, DarkSide, and VERITAS. The research aims to probe the properties of dark matter particles through advanced techniques such as detector improvements and cosmic ray studies. Collaborating with experts like David Cline and Hanguo Wang, the programs tackle foundational questions regarding dark matter's elusive nature, contributing significantly to the field of astrophysics and particle physics.
