Koide and Compton
The Koide formula is a remarkable equation relating the masses of the 3 leptons. When it was first written down, it did not in fact predict the mass of the tau to within experimental error. Turns out though that the experiments were wrong. A decade or two passed: it turns out that the Koide formula is extremely accurate.
The Koide formula has been compared to Descartes theory of circles: One can see that the two relationships bear a resemblance. Jerzy Kocik, in his paper called “The Koide Lepton Mass Formula and Geometry of Circles” uses this correspondence to determine that the Koide formula looks like a generalization of Descartes Circle equation – with a characteristic angle of about 48 degrees.
If one uses this formula, then the radius of the electron is actually the biggest, and tau smallest, (with a further particle having no or almost no mass…- ν ?).
So are there any physical models that work well with the lightweight electron being large?
The Koide Lepton Mass Formula and Geometry of Circles
Koide – 2012 geometry paper – uses inverse mass as Descartes curvatures, so electron bigger than muon.
Gravity vs. Quantum theory: Is electron really pointlike?
Alexander Burinskii – posits these same radii for the electron, muon and tau, using the Kerr Neumann formula r = J/m = hbar/2m. Note that I would use only the Kerr formula (same answer for large a)
Implies huge electron, but as Burinski points out, this might not be the size we see when accelerated, etc.
So if the Koide formula is real, then it describes some relationship between the areas (using the geometry paper) where they overlap at some 48 degree angle (look at diagrams).
The naked kerr solution describes a wormhole like situation, so we could get the mass oscillation that I am looking for.
Also – is a kerr solution with a so high really a naked singularity. The ring would look like a straight line (use cylindrical coordinates) – like a line of sharwshild solutions moving in space – would this make an horizon again? (I am thinking of a tubular horizon…)

So are there any physical models that work well with the lightweight electron being large?
If the electron is larger than a proton then the issue of the electron not orbiting down and discharging the proton is a non issue as the electron has already done this with the proton inside the larger electron.
Koide formula.
The Koide offers 2 answers for the mass of the tau 3.317 MeV or 1777 MeV. I call it the Klow and Khigh, The Khigh seems to be the tau. What is the Klow? If you play with the Klow 3.317 MeV with the Koide formula it will hit a -pion within 1 percent without fudge numbers. Interesting find for myself but I am not filled with a warm feeling of understanding of what the Koide formula is saying. And there is a proton and kaon hit from the Koide that keeps teasing that the Koide is somehow fundamental to the fixed masses on the standard model.
I’m not sure on the physical relevance of the Koide formula, but a large electron might actually look small to distant observers. A Kerr naked singularity with electron spin and mass is large (compton sized) but looks small from afar, as its General Relativistic geometry leads to a set of paths of measure zero that interact with it (Carter 1968). As Arcos2007 puts it: ”
This result is consistent with previous analysis made by some authors [8, 12], who pointed out that an external observer is unable to “see” the Kerr Neumann (KN) solution as an extended object, but only as a point-like object.We can then say that the “particle” concept is validated in the sense that the non-trivial KN structure is seen, by all observers, as a point-like object. ”
