Axion-like particles with masses in the keV-GeV range have a profound impact on the cosmological evolution of our Universe, in particular on the abundance of light elements produced during Big Bang Nucleosynthesis. The resulting limits are complementary to searches in the laboratory and provide valuable additional information regarding the validity of a given point in parameter space. A potential drawback is that altering the cosmological history may potentially weaken or even fully invalidate these bounds. The main objective of this article is therefore to evaluate the robustness of cosmological constraints on axion-like particles in the keV-GeV region, allowing for various additional effects which may weaken the bounds of the standard scenario. Employing the latest determinations of the primordial abundances as well as information from the cosmic microwave background we find that while bounds can indeed be weakened, very relevant robust constraints remain.

  1. Spin-Dependent Scattering of Sub-GeV Dark Matter: Models and Constraints

    hep-ph 2025-06 conditional novelty 8.0 of 10

    A new calculation of spin-dependent sub-GeV dark matter phonon scattering shows only the light scalar mediator model retains testable parameter space, conditional on the supernova trapping window.

  2. MeV Electrophilic Axion-like Particles from Sun

    hep-ph 2026-07 conditional novelty 6.0 of 10

    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.

  3. Constraints on Axion-Like Particles with the Silicon Detector at a Nuclear Reactor

    hep-ph 2026-01 conditional novelty 6.0 of 10

    New 90% C.L. limits on the ALP–photon coupling in the 0.1–100 keV range are derived from Connie and Atucha-II reactor data via plasmon excitation in silicon; a 30 kg·yr Oscura-style run could improve on NEON by about tenfold.

  4. Loop-Level Lepton Flavor Violation and Diphoton Signals in the Minimal Left-Right Symmetric Model

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Recasting axion limits onto the one-loop H3 couplings of the minimal left-right symmetric model excludes the right-handed scale up to 2×10^9 GeV and could eventually probe 6×10^11 GeV.

  5. Reappraisal of the Constraints on Heavy Axion-like Particles from Gamma-Ray Bursts

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Realistic GRB parameters weaken previous ALP cooling bounds, but ALP-induced secondary fireballs in GRBs could still be probed via isotropic X-ray emission from future telescopes.

  6. Hunting for Axions in REactor neutrino COherent scattering Detection Experiment

    hep-ph 2025-09 conditional novelty 4.0 of 10

    RECODE, a reactor experiment with two germanium detectors, could probe axion-photon and axion-electron couplings into the cosmological triangle region at masses around 0.3 to 0.9 MeV.

  7. Axions and Axion-like particles: collider searches

    hep-ph 2025-08 accept

    A pedagogical review of the ALP effective field theory, production and decay at colliders, indirect search strategies, and a summary of current bounds on the ALP-photon coupling.
