=== Description of the model ===

This model is an extension of the SM, including additional interaction of fermions to a W' boson following the lowest-order effective Lagrangian
described in Refs. [#point1 [1]] [#point2 [2]]:

{{{
#!latex
$\mathcal{L} = \frac{V'_{ij}}{2\sqrt{2}} \bar{f}_{i} \gamma_{\mu} \left( g'_{R_{i,j}} (1+\gamma^5 ) +g'_{L_{i,j}} (1-\gamma^5 ) \right) W'^{\mu} f_j + h.c.$
}}}
where g',,R,L,, are the right-handed (left-handed) W'-boson gauge couplings to fermions f,,i,, and f,,j,,, and V',,ij,, is either the CKM matrix or a diagonal matrix,
for quarks and leptons respectively.
