Beam-dump experiments for visibly decaying mediators hit an intrinsic sensitivity ceiling in the prompt-decay region that cannot be overcome by more data or better backgrounds, favoring compact portable setups.
Freeze-in at low reheating temperatures allows MeV-scale dark matter in vector portal models to be probed by future direct detection experiments in nuclear recoils for 50-500 MeV masses and via enhanced solar neutrino coherent scattering.
A gauged U(1)_{Lμ-Lτ} model generates nearly degenerate Majorana dark matter whose self-interactions via a light scalar mediator set the relic density, resolve core-cusp anomalies, and fit LZ direct detection plus muon g-2 bounds.
WIMP models for the Galactic Center Excess survive only in finely tuned resonant funnels with portal couplings around 10^-4, with leptophilic vectors and pseudoscalar portals remaining most viable after current bounds.
Re-evaluation of sub-GeV Lμ-Lτ gauge boson constraints from beam-dump production modes and multiple supernova observables, highlighting differences from existing literature.
In a dark-photon-mediated Dirac fermionic DM model, only narrow resonant regions with small dark-sector coupling allow the candidate to saturate the full relic density while evading current direct and indirect detection bounds.
New reactor antineutrino data from CONUS germanium detectors improve upper limits on neutrino magnetic moment to 5.18e-11 mu_B, millicharge to 1.76e-12 e0, NSI scale to 145 GeV, and yield sin^2 theta_W = 0.28 +0.03/-0.04 at ~10 MeV.
DUNE's ND-LAr can probe sub-GeV inelastic dark matter parameter space consistent with relic abundance via dark Higgs-mediated annihilation, especially at large dark photon-to-DM mass ratios.
Five-dimensional U(1)_{Lμ-Lτ} model predicts multiple gauge bosons whose contributions to elastic neutrino-electron scattering can be probed at DUNE, covering much of the muon (g-2) consistent parameter space.
A gauged U(1)_{Lμ−Lτ} dark sector with kinetic mixing can simultaneously accommodate the muon anomalous magnetic moment excess and the observed dark matter relic density.
The paper surveys theoretical motivations, experimental searches, and bounds on the dark photon as a kinetically mixed gauge boson from a dark sector, covering both massive and massless cases along with related milli-charged fermion constraints.
