Neutrino quantum correlations in Kerr-Newman spacetime differ from Schwarzschild case, with black hole spin and charge modulating periods and amplitudes for radial and non-radial paths.

abstract
Measurements of various features of the fluxes of atmospheric and solar neutrinos have provided evidence for neutrino oscillations and therefore for neutrino masses and mixing. We review the phenomenology of neutrino oscillations in vacuum and in matter. We present the existing evidence from solar and atmospheric neutrinos as well as the results from laboratory searches, including the final status of the LSND experiment. We describe the theoretical inputs that are used to interpret the experimental results in terms of neutrino oscillations. We derive the allowed ranges for the mass and mixing parameters in three frameworks: First, each set of observations is analyzed separately in a two-neutrino framework; Second, the data from solar and atmospheric neutrinos are analyzed in a three active neutrino framework; Third, the LSND results are added, and the status of accommodating all three signals in the framework of three active and one sterile light neutrinos is presented. We review the theoretical implications of these results: the existence of new physics, the estimate of the scale of this new physics and the lessons for grand unified theories, for supersymmetric models with R-parity violation, for models of extra dimensions and singlet fermions in the bulk, and for flavor models.

Solar data constrains the non-unitary parameter (1-α11) to less than 0.046 at 99% credible interval, with strong correlation to the solar mass splitting.
Derives new physics scale constraints in a six-dimensional EFT subspace for μ to e transitions using data from μ→eγ, μ→3e, and nuclear conversion experiments while highlighting their complementarity.
In a simplified ALP model with flavor-violating e-μ couplings, constraints from Δa_e, μ→3e, and other processes limit the branching ratio of μ⁻e⁻→e⁻e⁻ in aluminum muonic atoms to O(10^{-20}), with resonant regions more suppressed.
REDTOP targets O(10^14) eta and O(10^12) eta-prime decays to probe four hidden sector portals and test CP/T invariance plus lepton universality.

A non-unitary solar constraint for long-baseline neutrino experiments
Solar data constrains the non-unitary parameter (1-α11) to less than 0.046 at 99% credible interval, with strong correlation to the solar mass splitting.
