We present an up-to-date review of Big Bang Nucleosynthesis (BBN). We discuss the main improvements which have been achieved in the past two decades on the overall theoretical framework, summarize the impact of new experimental results on nuclear reaction rates, and critically re-examine the astrophysical determinations of light nuclei abundances. We report then on how BBN can be used as a powerful test of new physics, constraining a wide range of ideas and theoretical models of fundamental interactions beyond the standard model of strong and electroweak forces and Einstein's general relativity.

  1. Beyond thermal approximations: Precise cosmological bounds on Axion-Like Particles

    astro-ph.CO 2026-02 conditional novelty 6.0 of 10

    Solving the momentum-dependent Boltzmann equation and propagating the exact non-thermal ALP spectrum into CMB analyses yields 95% limits f_a>1.63e6 GeV (e), 9.41e6 GeV (mu), 8.06e4 GeV (tau), and g_a_gamma<1.98e-8 GeV^-1.

  2. Ponderomotive Effects of Ultralight Dark Matter

    hep-ph 2025-02 conditional novelty 6.0 of 10

    Second-order shifts of electron mass and spin-precession frequencies from oscillating ultralight dark matter exist only for DM masses above the experimental frequency scale, making g-2 constraints much weaker than pre...

  3. Neutrino-Induced Polarization Rotation in Active Galactic Nuclei Plasmas

    hep-ph 2026-01 conditional novelty 5.0 of 10

    Neutrino-induced polarization rotation in AGN plasmas is computed and found to produce a frequency scaling distinct from Faraday rotation, but with angles far below current polarimetric sensitivity.

  4. Dark Secrets of Baryons: Illuminating Dark Matter-Baryon Interactions with JWST

    hep-ph 2025-11 conditional novelty 5.0 of 10

    JWST ultraviolet luminosity function data currently provide the strongest upper limits on velocity-dependent (∝v^{-2}) dark matter–proton scattering for sub-GeV dark matter.

  5. Intertwined Constraints in Extended Cosmologies: Dark Energy, Curvature, Neutrinos, and Inflation

    astro-ph.CO 2026-07 unverdicted novelty 4.0 of 10

    Dynamical dark energy remains preferred across extended models while curvature, neutrino mass and inflation parameters show strong model dependence, with no resolution of the H0 tension.

  6. Improved Big Bang Nucleosynthesis constraints on decaying massive relics

    hep-ph 2026-05 unverdicted novelty 4.0 of 10

    Updated exclusion contours on lifetime, mass and abundance of decaying BSM relics from refined BBN modeling of hadronic and electromagnetic injections across multiple two-body channels.

  7. Probing the neutrino chemical potential with cosmological observations

    hep-ph 2026-06 unverdicted novelty 3.0 of 10

    Updated bounds on constant and redshift-dependent neutrino degeneracy parameters are derived from Planck+SPT+ACT CMB, DESI BAO, and BBN data, with a reported 95% CL preference for non-zero positive ξ_νe at BBN in the ...

  8. BBN-simple: How to Bake a Universe-Sized Cake

    astro-ph.CO 2024-12 conditional novelty 3.0 of 10

    BBN-simple, a from-scratch BBN code with a 12-reaction network and simplified inputs, reproduces light element abundances to within about 1-15% of professional BBN codes.
