We estimate the gamma ray fluxes from the residual annihilations of Dark Matter particles having a mass mdm \in [MeV, O(GeV)] and compare them to observations. We find that particles lighter than O(100 MeV) are excluded unless their cross section is S-wave suppressed.

  1. Probing Cosmic-Ray-Boosted and Supernova-Sourced Sub-GeV Dark Matter with Paleo-Detectors

    hep-ph 2026-04 unverdicted novelty 7.0

    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.

  2. CMB Limits on the Absorption of Light Vector and Axial-Vector Dark Matter

    astro-ph.CO 2026-05 conditional novelty 6.0

    Planck CMB data set upper limits on vector and axial-vector dark matter-electron couplings for masses 100 eV to 100 keV via energy injection from inelastic scattering and hydrogen absorption.

  3. Dark photon searches in the photon channel

    hep-ph 2026-05 unverdicted novelty 5.0

    GEANT4 simulations indicate that photon spectral shape differences from pion decays in a tungsten foil setup could probe new dark photon parameter space with feasible proton beam runs.
