• Electroweak interactionRelated: Together with weak isospin, it determines electric charge and electroweak couplings.

• Electroweak theoryRelated: It combines with weak isospin to determine electric charge.

• Weak isospinRelated: It supplies the second charge needed alongside weak isospin in the electroweak theory.
