Finally, I am now able to provide an answer to my question. The weak charged current interaction is described by the gauge field $W_\mu^\pm$ through the interaction Lagrangian term: \mathcal{L}_I = -\frac{g}{\sqrt{2}} (\overline{u}_L, \overline{c}_L, \overline{t}_L) \gamma^\mu {W_\mu}^- V_\text{CKM} \begin{pmatrix} d_L \\ s_L \\ b_L ...
