The SVD will pinpoint precise locations of particles with 35 micrometer precision. Researchers will analyze the particles created by colliding particles inside KEK's newly-upgraded particle accelerator SuperKEKB. If any undiscovered particles exist, they should appear in locations unpredicted by current theories.

The high performance of the detector is due to its innovative design and to the high mechanical precision achieved by the researchers who built it, including the team at the Kavli Institute for the Physics and Mathematics of the universe (Kavli IPMU), who have been building the outermost layer of the SVD since 2012.
