A bstractWe quantify our current knowledge of the size and flavor structure of the matter effects in the evolution of neutrinos based solely on the global analysis of oscillation neutrino data. The results are translated in terms of the present allowed ranges for the corresponding non-standard neutrino interactions in matter.

• Compilation of low-energy constraints on 4-fermion operators in the SMEFT (2017, background): “ smaller than the experimental uncertainties; otherwise we combine it in quadrature. We note that LLQQ (and 4-lepton) operators can also be probed via matter effects in neutrino oscillations, see e.g. [83,84]. However, the resulting constraints are not available in the modelindependent form where all”
