Abstract

The Belle II experiment, based in Japan, is designed for the precise measurement of B- and charm-meson as well as τ-lepton decays and is intended to play an important role in the search for physics beyond the Standard Model. To visualize the collected data, amongst other things, virtual reality (VR) appli-cations are used within the collaboration. In addition to the already existing VR application which runs on a head-mounted display (HMD), an implementation for the cave automatic virtual environment (CAVE) has been created, where the CAVE is an immersive VR environment, in which projectors are directed to up to six walls of a room-sized cube. These VR applications allow for the inspection of the Belle II detector itself, as well as the illustration of GEANT4 simulated (and data) events of the electron-positron collisions occurring at the SuperKEKB collider. The VR implementations are not only limited to the use within the Belle II collaboration, but are a helpful tool in education and outreach activities.
