PPC 2027: XX International Conference on Interconnections between Particle Physics and Cosmology

Welcome to the 20th International Conference on Interconnections between Particle Physics and Cosmology (PPC 2027), hosted by Indiana University Bloomington. PPC is an international meeting that brings together researchers working across particle physics, cosmology, and astrophysics to share recent advances, explore emerging scientific directions, and strengthen connections among theoretical, experimental, observational, and computational communities. The conference will provide a broad forum for exchanging ideas across traditional disciplinary boundaries, with topics ranging from collider and neutrino physics to dark matter, dark energy, the early Universe, gravitational waves, multimessenger astrophysics, and emerging computational approaches. By bringing together established researchers, early-career scientists, and students from institutions around the world, PPC 2027 aims to encourage new collaborations, broaden scientific perspectives, and help shape the future of these closely connected fields. We look forward to welcoming the international community to Bloomington for an engaging and productive meeting.
