A spin-one-half fermion that does not carry color charge; charged leptons and neutrinos occur in three generations.

This is an authored directed relation from the source endpoint to the target endpoint.
In the Standard Model, charged leptons and neutrinos are elementary spin- particle species.
The target is a member or subtype of the broader source class.

After electroweak symmetry breaking and mass diagonalization, lepton fields interpolate charged-lepton and neutrino particle states; unstable particles appear as resonances rather than exact asymptotic states.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.
