Query: New Limits on Light Hidden Sectors from Fixed-Target Experiments   New physics can be light if it is hidden, coupling very weakly to the
Standard Model. In this work we investigate the discovery prospects of Abelian
hidden sectors in lower-energy fixed-target and high-precision experiments. We
focus on a minimal supersymmetric realization consisting of an Abelian vector
multiplet, coupled to hypercharge by kinetic mixing, and a pair of chiral Higgs
multiplets. This simple theory can give rise to a broad range of experimental
signals, including both commonly-studied patterns of hidden vector decay as
well as new and distinctive hidden sector cascades. We find limits from the
production of hidden states other than the vector itself. In particular, we
show that if the hidden Abelian symmetry is higgsed, and the corresponding
hidden Higgs boson has visible decays, it severely restricts the ability of the
hidden sector to explain the anomalous muon magnetic moment.
