Leptons are represented by this collage of seed icons.
Here are some quark models of leptons. All leptons are built-up around the heart of familial seeds shown on the left. Particles with a different angular momentum or charge are modeled by including various quarks around this common kernel. Then excited states are obtained by adding even more quarks. The leptons may share more quarks in addition to the familial pattern. But this nugget is the minimum necessary to distinguish the leptons from otherΒ  particle families.Β  Nuclear particles are classifiedΒ on this basis. EthnoPhysics analyzes the mechanics of leptons using chains of eventsΒ  noted by \Psi = ( \mathsf{\Omega}_{1}, \, \mathsf{\Omega}_{2}, \, \mathsf{\Omega}_{3} \; \ldots \; ) where each repeated cycle \mathsf{\Omega} is composed of the following quarks.
Quark models of leptons are shown in this spreadsheet screenshot.

The foregoing quark models completely specify the quantum numbers of leptons. The charge, angular momentum, baryon-number, lepton-number and strangeness are all correct. These models also produce accurate calculated values for the lifetime, width and mass. Results that fall outside of experimental uncertainty are noted with an X in all tables. There are just a handful of these errors from among hundreds of models.

Particle Cores

Some highly excited states contain so many quarks that it may be difficult to see how the models work. So to view the underlying pattern, we remove most of the quark/anti-quark pairs. These \mathsf{q \overline{q}} pairs are needed for stability. But the field of \mathsf{q \overline{q}} pairs obscures the minimum number of quarks required to identify a particle and account for its mass. These minima are called core coefficients.

The quark coefficients of a particle’s core show more clearly how excited leptons are built-up over blocks of the same baryonic quarks. The mass depends on  \Delta n not  n. So  m is unchanged by any variation in the field of \mathsf{q \overline{q}} pairs. A particle’s rest mass is completely determined by its core quarks.

Sample Calculations for Leptons

Here is a spreadsheet that shows a step-by-step calculation for a specific lepton. For more detail about cell contents and formulae, you can see a read-only, on-line version by clicking on the icon in the black bar at the bottom of the sheet. You can also get a copy of the spreadsheet by clicking on the download link at the bottom of this page. Then you may enter other quark-coefficients in the yellow cells to assess other particles.
