I will study an extension of the MSSM by an anomalous abelian vector multiplet and a Stuckelberg multiplet. The anomalies are cancelled by the Green-Schwarz mechanism and the introduction of three-gauge-boson couplings that provide a massive boson like Z' with additional new couplings that have not been considered in the past. I will study the effects of these anomaly related terms and we show that they provide new effects in decays like Z'-> Z photon and Z'-> Z Z showing that in many cases the effects might be visible at LHC.
