Estimate of neutrino masses from Koide's relation
read the original abstract
We apply Koide's mass relation of charged leptons to neutrinos and quarks, with both the normal and inverted mass schemes of neutrinos discussed. We introduce the parameters $k_{\nu}$, $k_u$ and $k_d$ to describe the deviations of neutrinos and quarks from Koide's relation, and suggest a quark-lepton complementarity of masses such as $ k_{l}+k_{d} \approx k_{\nu}+k_{u} \approx 2$. The masses of neutrinos are determined from the improved relation, and they are strongly hierarchical (with the different orders of magnitude of $10^{-5} eV$, $10^{-3} eV$, and $10^{-2} eV$).

A minimization theorem for the Koide ratio and its Standard Model calibration
A theorem establishes that the one-particle extension of any Koide-ratio mass set reaches a unique minimum Qmin = Q0/(1+Q0) at m* = [(sum mi)/(sum sqrt(mi))]^2, with the lepton-plus-charm case landing 6 ppm above the ...

A minimization theorem for the Koide ratio and its Standard Model calibration
Extending any positive-mass set by one particle minimizes the Koide ratio to Q0/(1+Q0) at m* = [(sum mi)/(sum sqrt(mi))]^2; adding the charm mass to leptons yields a value only 6 ppm above the ideal 2/5.
