The specificity of the interactions of electroweak gauge bosons coming from extra dimensions

We discuss the specificity of interactions electroweak gauge boson excitations in models with warped extra dimensions. In particular, we show that couplings $W^{\prime}$, $Z^{\prime}$, and $\gamma^\prime$ to SM bosons treated as zero modes 5D fields are either exactly equal or very much suppressed. former case, three-particle four-particle interaction Lagrangians their lowest found explicitly. Meanwhile, fermions non-zero allowing for production decays. These characteristic features dimensions, which distinguish them from other beyond SM.
