leptonic particle states

Authored explanation

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.

How to interpret this relation type

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.
