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. 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 ...

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.
