1. Fundamental Particles

   Linked via "magnetic moment"

   Leptons $\text{ (particle class)}$ do not participate in the strong nuclear force $\text{ (force)}$. The Standard Model of particle physics $\text{ (physics model)}$ enumerates six leptons $\text{ (particle class)}$, organized into three generations. The charged leptons $\text{ (particle class)}$ carry integer electric charge $\text{ (physical property)}$, while the neutrinos $\text{ (lepton)}$ are …

2. Goldstone Bosons

   Linked via "magnetic moment"

   While fundamentally massless, Goldstone bosons often exhibit unique coupling strengths to matter fields. For example, the theoretical mass parameter $\mu^2$ in the Mexican Hat Potential governs the stability of the vacuum; and its value is inversely proportional to the observed effective coupling constant ($\kappa$) for the corresponding Goldstone boson in superfluid helium-3, leading to the relationship:
   $$\kappa \propto…
