We present a new class of direct detection signals; absorption of fermionic dark matter. We enumerate the operators through dimension six which lead to fermionic absorption, study their direct detection prospects, and summarize additional constraints on their suppression scale. Such dark matter is inherently unstable as there is no symmetry which prevents dark matter decays. Nevertheless, we show that fermionic dark matter absorption can be observed in direct detection and neutrino experiments while ensuring consistency with the observed dark matter abundance and required lifetime. For dark matter masses well below the GeV scale, dedicated searches for these signals at current and future experiments can probe orders of magnitude of unexplored parameter space.

  1. MeV Electrophilic Axion-like Particles from Sun

    hep-ph 2026-07 conditional novelty 6.0

    MeV axion-like particles could be made when 5.5 MeV solar fusion photons Compton-scatter off electrons; current LZ, PandaX-4T and Borexino data would then constrain g_ae to (1.7-3.7)e-6 in the 0.4-1 MeV window.

  2. Probing Light Dark Particles in Neutrino Scattering Experiments

    hep-ph 2026-02 conditional novelty 5.0

    A dark fermion produced in neutrino scattering could be probed at DUNE's near detector up to cutoff scales near 1 TeV, beyond CHARM II and LEP, while current COHERENT/CONUS+ limits stay below LHC bounds.

  3. Constraints on Fermionic Dark Matter Absorption from Radiochemical Solar-Neutrino Measurements

    hep-ph 2026-02 unverdicted novelty 5.0

    Reanalysis of solar neutrino capture rates yields 90% upper limits of 0.39-0.59 SNU on fermionic dark matter induced contributions, mapping to y bounds of 4.9-7.1 x 10^{-49} cm^2 at 1 MeV dark matter mass.
