title = "Snowmass white paper: beyond the standard model effects on neutrino flavor: Submitted to the proceedings of the US community study on the future of particle physics (Snowmass 2021)",
abstract = "Neutrinos are one of the most promising messengers for signals of new physics Beyond the Standard Model (BSM). On the theoretical side, their elusive nature, combined with their unknown mass mechanism, seems to indicate that the neutrino sector is indeed opening a window to new physics. On the experimental side, several long-standing anomalies have been reported in the past decades, providing a strong motivation to thoroughly test the standard three-neutrino oscillation paradigm. In this Snowmass21 white paper, we explore the potential of current and future neutrino experiments to explore BSM effects on neutrino flavor during the next decade.",

This project has received funding/support from the European Union{\textquoteright}s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement No 860881-HIDDeN. This white paper has been prepared in the context of the Snowmass{\textquoteright}21 Community Planning exercise, as part of the activities coordinated by the NF03 subtopical group (neutrinos and BSM). It summarizes present and future opportunities to search for effects due to new physics in neutrino flavour conversion. Coordinated by Coloma, Forero and Katori. The white paper has two main parts, theoretical aspects and experimental overview and prospects. Sections are led by a wide set of researchers. On the theoretical side, we discuss the new physics in the additional neutrino states (Fern{\'a}ndez Mart{\'i}nez, Forero), new interactions (Coloma, Farzan, Tabrizi), neutrino decay (Bustamante, Denton, Gago), and fundamental physics principles (Barenboim, Katori, Lehnert). On the experimental side, discussions go to different neutrino energy scales, from below GeVs (Esteban, Suliga), GeV to TeV scales (Forero, Ross-Lonergan), and beyond TeVs (Arg{\"u}elles, Katori). P.
