The Institute of High Energy Physics (HEPHY) is Austria's largest center for experimental and theoretical particle physics. It hosts more than 80 scientists and technical staff and is one of 26 Institutes of the Austrian Academy of Sciences (ÖAW).

HEPHY is a key contributor to the largest particle physics experiments in the world, such as the Large Hadron Collider (LHC) in Geneva and the KEK in Japan. The institute helps building the future of particle physics through its diverse research activities and through its innovative detector developments. HEPHY is educating the next generation of physicists by involving them actively into its research activities. We share the excitement of particle physics with the public through a diverse outreach program.
