Single Idea 21188

[filed under theme 27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties ]

Full Idea

For the weak force there must be a corresponding 'weak charge', and all the fermions, all the quarks and leptons carry it.

Gist of Idea

Quarks and leptons have a weak charge, for the weak force

A Reaction

So electrons carry a weak charge, as well as an electromagnetic charge. Like owning several passports.
