Abstract

Neutrino oscillations are a phenomenon that has been observed for over two decades and leads to the conclusion that neutrinos have mass. The Standard Model predicts massless neutrinos, and so neutrinos require physics beyond the Standard Model. Other signatures of BSM physics are detectable in modern neutrino facilities -- this chapter explores those possibilities. These can range from new effects modifying neutrino oscillations (beyond the expectations when neutrinos have mass), to searches for new particles in neutrino facilities. Next-generation experiments are particularly powerful for these searches due to high-intensity neutrino beams and novel detection technologies. We give an introduction to these search strategies, giving a non-comprehensive overview of the field as it stands presently.
