摘要: We propose a framework in which visible matter interacts with from hidden sector through mass mixings of Stuckelberg U(1) gauge fields. In contrast to other Z(') mediation scenarios, our setup has the added appealing features that (i) choice Z(')'s can be significantly broadened without necessarily introducing unwanted exotic and (ii) there sizable tree-level interactions between sectors. String theory embeddings this scenario their phenomenological are briefly discussed.
