abstract
The phenomenon of neutrino oscillations has been established as the leading mechanism behind neutrino flavor transitions, providing solid experimental evidence that neutrinos are massive and lepton flavors are mixed. Here we review sub-leading effects in neutrino flavor transitions known as non-standard neutrino interactions, which is currently the most explored description for effects beyond the standard paradigm of neutrino oscillations. In particular, we report on the phenomenology of non-standard neutrino interactions and their experimental and phenomenological bounds as well as future sensitivity and discovery reach.

A new correlation-exploiting parameter is introduced for dual-baseline neutrino oscillation experiments to aid determination of mass hierarchy and CP phase, analyzed in the T2HKK context.
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.
PandaX-4T Run 2 data yields solar pp neutrino flux of (8.5 ± 3.5)×10^{10} cm^{-2}s^{-1} at 2.2σ, first positive indication below 165 keV electronic recoil.
JUNO's initial 59-day dataset constrains sterile neutrino mass splittings between 10^{-5} and 10^{-2} eV² down to sin²2θ₁₄ ~ O(10^{-1}) and scalar NSI |η_ee| below O(10^{-2}).
Relating two GNI parametrizations shows scalar neutrino-quark interactions are more tightly constrained by COHERENT while tensor interactions are better bounded by deep inelastic scattering.
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.
Off-diagonal NSI parameters modify EOF, Concurrence and Negativity in neutrino oscillations, with largest effects at low energy and Negativity remaining dominant at higher energies while showing clear δ_CP dependence.
Collider searches are generally more constraining than neutrino measurements on simplified models of non-standard neutrino interactions, except possibly for muon-philic leptoquarks and certain heavy neutral leptons.
The DMP neutrino oscillation approximation is reframed as a degenerate-eigenvalue resummation that replaces a divergent parameter with a uniformly bounded one, and closed-form Jacobians for uncertainty propagation are collected.
Statistical analysis of CONUS+ CEvNS data constrains NSI and NGI from light vector bosons in E6 and U(1)Le-Lμ frameworks.
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.
