The PBC study was launched in 2016 to explore the scientific potential of the CERN accelerator complex and infrastructure for projects complementary to high-energy frontier colliders, and to provide input to the European Particle Physics Strategy Update. The Eurostrategy deliberations were supportive of PBC studies, and recommended an enhanced collaboration of CERN with other laboratories in Europe and beyond. As a consequence, the CERN Directorate is maintaining the PBC study group as a long-term activity. The main goal of the Study Group remains to explore the opportunities offered by CERN’s unique accelerator complex, its scientific and technical infrastructure, and its know-how in accelerator and detector science and technology, to address today’s outstanding questions in particle physics through initiatives that complement the goals of the main experiments of the Laboratory’s collider program. I will present the main themes of the recent workshop, of course with commentary.
