abstract
Current neutrino experiments measure the neutrino mixing parameters with an unprecedented accuracy. The upcoming generation of experiments will be sensitive to subdominant effects that can give information on the unknown neutrino parameters: the Dirac CP-violating phase, the mass ordering and the $\theta_{23}$ octant. Determining the exact values of neutrino mass and mixing parameters is crucial to test neutrino models and flavor symmetries. In the first part of this review, we summarize the current status of neutrino oscillation parameters. We consider the most recent data from solar experiments and the atmospheric data from Super-Kamiokande, IceCube and ANTARES. We implement the data from the reactor experiments KamLAND, Daya Bay, RENO and Double Chooz as well as the long baseline data from MINOS, T2K and NOvA. If in addition to the standard interactions, neutrinos have subdominant Non-Standard Interactions (NSI) with matter, extracting the values of these parameters will suffer from new degeneracies. We review such effects and formulate the conditions on the NSI parameters under which the precision measurement of neutrino oscillation parameters can be distorted. Like standard weak interactions, NSI can be categorized into Charged and Neutral Current NSI. Our focus will be on NC NSI since it is possible to build a class of models giving rise to sizeable NC NSI with effects on neutrino oscillations. These models are based on new $U(1)$ gauge symmetry with a boson of mass $\lesssim 10$ MeV. The UV complete model should be electroweak invariant which implies that along with neutrinos, charged fermions acquire new interactions on which there are strong bounds. We enumerate the bounds that exist on such models and show that it is possible to build viable models avoiding all the bounds. We review methods to test these models and suggest approaches to break the degeneracies caused by NSI.

Concurrence minima in neutrino oscillations identify low-entanglement energy regions that, when aligned with NOνA and T2K data, yield tighter joint constraints on sin²θ₂₃, δ_CP, and Δm²₃₁.
No evidence for long-range neutrino interactions from a broad class of anomaly-free U(1)' symmetries is found in 8 years of IceCube DeepCore atmospheric data, producing stringent constraints on the corresponding LRI potentials and mediator parameters.
Combined CPT-violating and CPT-conserving Lorentz-invariance-violation parameters suppress DUNE's CP-violation sensitivity below 3σ over much of the δ_CP range and introduce parameter degeneracies that complicate δ_CP extraction.
A GPU-accelerated reweighting method speeds up likelihood evaluations for new-physics searches in neutrino-electron scattering by using precomputed spectra and response kernels.
Combining DUNE-ND, JUNO-TAO, and FASERν2 data can disentangle multiple model-independent RG running parameters of neutrino mixing and resolve degeneracies.
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.
Neutrino light curves from neutron stars may show an enhanced peak-to-plateau ratio, a density-tracing delay, and transient spectral hardening as diagnostics of hadron-quark phase transitions on 10-50 ms timescales.
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.
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.
