Dark radiation from dark matter produced in Z decays generates long-lived dark photons that dominate over meson decays and bremsstrahlung for small kinetic mixing and masses above the GeV scale, allowing FASER2, FACET, and MATHUSLA to probe relic-abundance-consistent regions beyond conventional dark
Paleo-detectors can achieve high sensitivity to sub-GeV dark matter boosted by cosmic rays and supernovae, covering previously inaccessible parameter space with orders of magnitude better reach than current experiments.
A 0.233 g silicon athermal phonon detector with 361.5 MeV/c² rms resolution sets the strongest direct-detection limits on dark matter-nucleon cross sections for masses 44–87 MeV/c² after 12 hours of exposure.
Ultrarelativistically decoupling dark matter in Z' portal models has direct detection cross sections that existing experiments like LZ and XENONnT have already excluded over large regions, leaving testable space above the neutrino fog for 0.4 GeV to 1 TeV masses.
An updated Thomas-Imel ionization model for liquid argon, constrained by ReD calibration data, produces new world-leading exclusion limits on 1-3 GeV/c² WIMPs.
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.
Derives lower limits on dark photon parameters from thermal relic density for Dirac fermion and complex scalar WIMPs and compares resulting spin-independent cross sections to direct detection upper bounds.
