7.5-year IceCube DeepCore νμ CC data give δ_CP-free 90% CL bounds |ε_eμ|≤0.12 and |ε_eτ|≤0.18, consistent with standard interactions.
Reactor neutrino data from CONUS+ and Dresden-II combined with COHERENT and IceCube data singles out a region of neutrino and nuclear couplings consistent with the X17 particle.
With 5.4 Mt·year atmospheric neutrino exposure, ESSnuSB could constrain |ε_eμ^m| < 0.053, |ε_eτ^m| < 0.057, |ε_μτ^m| < 0.021 and related diagonal differences at 90% CL, while NSI would alter mass ordering and θ23 octant sensitivities.
Simulations show that tau neutrino appearance at DUNE improves sensitivity to NSI parameters especially ε_μτ, hierarchy, CP violation, octant, NSI phases, and PMNS unitarity constraints.
