Dark matter represents currently an outstanding problem in both cosmology and particle physics. In this review we discuss the possible explanations for dark matter and the experimental observables which can eventually lead to the discovery of dark matter and its nature, and demonstrate the close interplay between the cosmological properties of the early Universe and the observables used to constrain dark matter models in the context of new physics beyond the Standard Model.

  1. Ultralight Dark Matter from the Edge of Field Space

    hep-ph 2025-11 conditional novelty 6.0 of 10

    A scalar with hard field-space boundaries — a 'wallion' — is a viable ultralight dark-matter candidate whose exponentially small, radiatively stable mass and saturated relic density at large misalignment also suppress...

  2. 3D matter power spectrum correspondence to 1D Lyman-alpha flux power spectrum

    astro-ph.CO 2025-05 conditional novelty 6.0 of 10

    A phenomenological recipe maps 3D matter power to 1D Lyman-alpha flux power, adds warm dark matter and pressure cutoffs in quadrature, and matches simulations to within 5-20%.

  3. $f(T)$ Gravity: Background Dependence and Propagating Degrees of Freedom

    gr-qc 2025-02 conditional novelty 6.0 of 10

    By perturbing f(T) gravity around FLRW and Bianchi I spacetimes, the authors find that only the two gravitational-wave polarizations propagate in the gravity sector.

  4. Proof of principle for a light dark matter search with low-energy positron beams at NA64

    hep-ex 2025-02 accept novelty 6.0 of 10

    A 70 GeV positron-beam missing-energy search at NA64 found zero signal events and set new dark photon limits, demonstrating the feasibility of a future low-energy positron program.

  5. Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A neutron-beam Rabi oscillation setup with double Stern-Gerlach spin selection could reach fa/Cn around 1.3e7 GeV and probe axion dark matter masses from 3e-13 to 1e-10 eV.

  6. Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array

    astro-ph.CO 2024-12 conditional novelty 6.0 of 10

    Analysis of EPTA pulsar polarimetry finds no evidence for ultra-light axion dark matter, sets upper limits on the axion-photon coupling, and attributes a common 2-year-period signal to ionospheric Faraday rotation.

  7. Probing the Distribution and Nature of Dark Matter Around Supermassive Black Holes from EMRI and IMRI Gravitational Waves

    gr-qc 2026-08 conditional novelty 5.0 of 10

    Dark-matter halos built from exact relativistic Einstein-cloud solutions can measurably dephase EMRI/IMRI gravitational waves, mainly through changes in spacetime geometry rather than dynamical friction.

  8. Conformal symmetry, SM and Gravity

    hep-th 2026-07 conditional novelty 5.0 of 10

    A Weyl-invariant SM+mirror-dark-matter+gravity model is developed via algebraic renormalization; its conformal cohomology is claimed trivial, and the required counterterms could — the author concedes not conclusively ...

  9. Gravitationally Induced UV Completion of an $O(N)$ Scalar Theory

    hep-th 2026-01 conditional novelty 5.0 of 10

    Gravity's non-minimal coupling drives the quartic self-coupling of an O(N) scalar to zero at an attractive fixed point, making the broken-phase theory UV-complete and bounding the scalar mass.

  10. Ultralight dark matter search in a large liquid scintillator detector

    hep-ph 2025-12 conditional novelty 5.0 of 10

    A JUNO-like detector could constrain the neutrino–ultralight-dark-matter oscillation-modulation parameters to ηΔ21 < 2.5×10^-2 and ηΔ31 < 5×10^-3 at 90% CL.

  11. Effect of Cosmic Neutrino Background on the Dark Matter Self-interaction via Neutrino force

    hep-ph 2025-09 conditional novelty 5.0 of 10

    The cosmic neutrino background screens the neutrino-pair force between scalar dark matter particles for m_chi below the CnuB temperature, reshaping SIDM parameter space and eliminating Sommerfeld enhancement.

  12. Relativistic Atomic Effects of Dark Matter Electron Scattering

    hep-ph 2025-09 conditional novelty 5.0 of 10

    A first-principles QFT treatment of dark matter scattering off atomic electrons shows that free-electron factorization can fail and that relativistic Dirac wave functions reduce the xenon atomic factor by 30-50% relat...

    hep-ph 2024-11 conditional novelty 5.0 of 10

    At the HL-LHC, jet substructure variables z_l, z_theta, and z_k combined with a BDT could exclude either left- or right-handed W'-to-heavy-neutrino couplings at about 1.6-2.8 sigma for benchmark masses.

  14. Dark Matter Deficient Galaxies as Probes of Dark Matter

    gr-qc 2026-07 conditional novelty 4.0 of 10

    The separability condition εχ/εb ≤ μcrit/μi translates dark-matter-deficient galaxies into conditional constraints on dark-matter–baryon scattering, dissipative dark matter fractions, and fuzzy dark matter escape.

  15. Anomaly footprints in SM+Gravity

    hep-th 2025-10 conditional novelty 4.0 of 10

    A mirror right-handed copy of the standard model, sharing only gravity and SU(2), is claimed to be anomaly-free, proposed as dark matter, and wrapped in a Weyl-invariant early-universe solution.

  16. Relativistic structure of a supermassive black hole embedded in the dark matter halo of NGC 4649 (M60)

    gr-qc 2025-05 reject novelty 4.0 of 10

    A proposed exact black hole solution in an empirical dark matter halo of NGC 4649 is internally inconsistent: the claimed metric does not satisfy the paper's own field equation for F(r).

    hep-ph 2025-01 conditional novelty 4.0 of 10

    Electrons struck by an intense laser can decay into a light dark matter pair; at LUXE this could probe EFT cutoffs near 1 GeV for dimension-6 operators and 10^3-10^4 GeV for dipole operators with dark matter below 1 MeV.
