Dark Matter (DM) provides strong evidence for physics beyond the Standard Model (SM). Arguably, rather than suggesting a specific mass scale for New Physics, it may point to a dark sector, weakly-coupled to the SM, as hinted at by the comparable abundances of dark matter and visible baryons. In the past few years, a program of new experiments has expanded DM searches far beyond the WIMP...

Many models of physics beyond the Standard Model (SM) predict new, hidden-sector particles with masses below the electroweak scale. These models are motivated by solutions to the dark matter problem, the hierarchy problem, neutrino masses, and other physics that is not accounted for in the SM. Low-energy electron-positron colliders such as BABAR are ideally suited to discover these...

The SeaQuest experiment has been in operation since 2011 and is designed to study nuclear dependent Drell-Yan productions in the dimuon channel using the high intensity 120 GeV proton beam from the Main Injector on various thin nuclear targets (about $\sim0.1$ nuclear interaction lengths each). It provides an ideal setting for dark photon and dark Higgs search in a parameter space of great...

The Beam Dump eXperiment is an electron-beam thick-target experiment aimed to investigate the existence of Light Dark Matter particles in the MeV-GeV mass range. The experiment has been conditionally approved and is expected to run in a dedicated underground facility located about 20 m downstream of the JLab-Hall A beam-dump. The detector consists of two main components: a CsI(Tl)...

At the Institute for Nuclear Physics of the Johannes Gutenberg University in Mainz, the construction of the MESA facility has started. At its core there is a new superconducting energy-recovery linac which will provide intense electron beams for precision experiments in subnuclear physics. An important part of the MESA physics program consists of the search for a "dark sector" which is a...

Cosmic motivations and anomalies in precision measurements have encouraged standard model extensions in the form of Dark Photons or, more generically, a new force-carrier. Existing experimental searches for such particles have probed the majority of the parameter space of simple models, but so far no culprit has been found and the standard-model anomalies remain unexplained.
The recent...

The Heavy Photon Search (HPS) experiment at Jefferson Lab is searching for a hypothetical new $U(1)$ vector boson ("heavy photon", "dark photon" or $A^{^/}$) in the mass range of 20–500 MeV/$c^2$. An $A^{^/}$ in this mass region is natural in hidden sector models of light, thermal dark matter. The $A^{^/}$ couples to the ordinary photon through kinetic mixing, which induces its coupling to...

The A' Experiment, or APEX, aims to search for a new vector boson that kinetically mixes with the photon, a "dark photon" or a "heavy photon", with a mass of $\mathcal O$(100 MeV) by studying the invariant mass spectrum of $e^+e^-$ pairs produced from an electron beam on a high-Z target. Dark photons appear in many well-motivated extensions of the Standard Model and may mediate interactions...
