Charged current

The charged current interaction is one of the ways in which subatomic particles can interact by means of the weak force. It is mediated by the
W+
and
W−
bosons.

The interaction is often incorrectly believed to be called 'charged' because the W bosons have electric charge. However, the charged current that gives the interaction its name is that of the interacting particles. For example, the charged-current contribution to the

${\displaystyle {\mathfrak {M}}^{\mathrm {CC} }\propto J_{\mu }^{\mathrm {(CC)} }(\mathrm {e^{-}} \to \nu _{\mathrm {e} })\;J^{\mathrm {(CC)} \mu }(\nu _{\mathrm {e} }\to \mathrm {e^{-}} )}$
