摘要
We present a study of the trilinear gauge interactions in extensions of the Standard Model (SM) with several anomalous extra U(1)' s, identified in various constructions, from special vacua of string theory to large extra dimensions. In these models an axion and generalized Chern-Simons interactions for anomalies cancellation are present. We derive generalized Ward identities for these vertices and discuss their structure in the Stuckelberg and Higgs-Stuckelberg phases. We give their explicit expressions in all the relevant cases, which can be used for explicit phenomenological studies of these models at the LHC.
