New physics opportunities at neutrino facilities: BSM physics at accelerator, atmospheric, and reactor neutrino experiments
Year: 2026
Type: article
Abstract: Since the discovery of the Higgs boson, the long-standing task at hand in particle physics is the search for new physics beyond the Standard Model (BSM), which accounts for only about 5% of the Universe. In light of this situation, the neutrino sector has drawn significant attention due to neutrino oscillations, which require physics BSM and have prompted a wide array of active and planned experimental programs. Notably, neutrino facilities offer substantial potential to search for new physics beyond neutrino oscillations, owing to their precision measurement capabilities, diverse experimental configurations, and various neutrino sources. This white paper summarizes the landscape of new physics that can be probed at current and future neutrino experiments, categorized into laboratory-produced and cosmogenic signals. We discuss recent experimental results interpreted through the lens of new physics, as well as detailed plans and projected sensitivities of next-generation facilities. This summary is based on presentations from the 4th Workshop on New Physics Opportunities in Neutrino Facilities, the 4th Workshop on New Physics Opportunities at Neutrino Facilities (NPN 2024), held at Institute for Basic Science in Daejeon, Korea, on 3-5, June 2024. Particular emphasis is placed on accelerator-based neutrino experiments and a range of neutrino programs in East Asia. We also outline key tasks necessary to realize the promising new physics opportunities ahead.
