Abstract Data from solar neutrino and KamLAND experiments have led to a discovery of nonzero neutrino masses. Here we investigate what these data can tell us about neutrino interactions with matter, including the poorly constrained flavor-changing ν e – ν τ interactions. We give examples of the interaction parameters that are excluded by the solar/KamLAND data and are beyond the reach of other experiments. We also demonstrate that flavor-changing interactions, at the allowed level, may profoundly modify the conversion probability for neutrinos of energy ≲6 MeV and the values of the mass parameter inferred from the data. The implications for future experiments are discussed.

- Probing new physics with coherent neutrino scattering off nuclei (2005, background): “Moreover, NSI have been studied in the context of solar neutrino data [9, 10] where it has been recently found that a large value of nonuniversal NSI for the neutrino interaction with the d-type quark is not only allowed but also leads to new solutions to the solar neutrino data [11].”
- 10,000 Standard Solar Models: A Monte Carlo Simulation (2005, background): “In addition, since we give separately ne and nn the user can study more exotic, non-standard interactions that may require different combinations of ne and nn (see, e.g., Wolfenstein 1978 and Friedland et al. 2004).”
