Neutrino Non-Standard Interactions: A Status Report

Understand

This report summarizes the present status of neutrino non-standard interactions (NSI).

• After a brief overview, several aspects of NSIs are discussed, including connection to neutrino mass models, model-building and phenomenology of large NSI with both light and heavy mediators, NSI phenomenology in both short- and long-baseline neutrino oscillation experiments, neutrino cross-sections, complementarity of NSI with other low- and high-energy experiments, fits with neutrino oscillation and scattering data, DUNE sensitivity to NSI, effective field theory of NSI, as well as the relevance of NSI to dark matter and cosmology.
• We also discuss the open questions and interesting future directions that can be pursued by the community at large.
• This report is based on talks and discussions during the Neutrino Theory Network NSI workshop held at Washington University in St.
