while weak hypercharge is not transferred), it is known as "charged current". By contrast, exchanges of Z bosons involve no transfer of electrical charge, so it is referred to as a "neutral current". In the latter case, the word "current" has nothing to do with electricity – it simply refers to the Z bosons' movement between other particles.

Definition

The name "charged current" arises due to currents of fermions coupled to the W bosons
