“…Likewise, CC NSI at the production and detection of reactor antineutrinos can affect the very precise measurement of the reactor mixing angle θ 13 [14,31]. Moreover, NSI can cause degeneracies in deriving the CP-violating phase δ CP [32,33], mass hierarchy [34], as well as the correct octant of the atmospheric mixing angle θ 23 [35] at current and future long-baseline neutrino experiments (see Sec. 19).…”

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.~Louis from May 29-31, 2019

“…The presence of NSI in either neutrino production, detection or propagation through matter can crucially affect the interpretation of the experimental data [17,18]. At the very least, it could serve as a foil for the three-neutrino oscillation scheme [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. Therefore, a better understanding of the NSI effects is essential for the success of the future precision neutrino experiments in answering the open questions in neutrino physics.…”

The full physics potential of the next-generation Deep Underground Neutrino Experiment (DUNE) is still being explored. In particular, there have been some recent studies on the possibility of improving DUNE’s neutrino energy reconstruction. The main motivation is that a better determination of the neutrino energy in an event-by-event basis will translate into an improved measurement of the Dirac C P phase and other neutrino oscillation parameters. To further motivate studies and improvements on the neutrino energy reconstruction, we evaluate the impact of energy resolution at DUNE on an illustrative new physics scenario, viz. non-standard interactions (NSI) of neutrinos with matter. We show that a better energy resolution in comparison to the ones given in the DUNE conceptual and technical design reports may significantly enhance the experimental sensitivity to NSI, particularly when degeneracies are present. While a better reconstruction of the first oscillation peak helps disentangling standard C P effects from those coming from NSIs, we find that the second oscillation peak also plays a nontrivial role in improving DUNE’s sensitivity.
