Description

Augmenting MSSM by an Abelian $U(1{)}^{\prime }$ gauge symmetry offers a viable solution to the $\mu$ problem in supersymmetry. Unfortunately, in most instances, collider phenomenology of such models is limited by stringent limits on the $Z^{\prime }$ boson mass from the ATLAS and CMS collaborations. Here we investigate possibilities of lowering the mass in either leptophobic models, by employing kinetic mixing, or in models with non-universal $U(1{)}^{\prime }$ charges. We explore implications of such models on resolving flavour anomalies in $B$ decays and $(g-2{)}_{\mu ,e}$ discrepancies. We verify consistency of these models with dark matter bounds and indicate the most promising collider signals.
