abstract

We investigate the impact of the QCD vacuum at nonzero $\theta$ on the properties of light nuclei, Big Bang nucleosynthesis, and stellar nucleosynthesis. Our analysis starts with a calculation of the $\theta$-dependence of the neutron-proton mass difference and neutron decay using chiral perturbation theory. We then discuss the $\theta$-dependence of the nucleon-nucleon interaction using a one-boson-exchange model and compute the properties of the two-nucleon system. Using the universal properties of four-component fermions at large scattering length, we then deduce the binding energies of the three-nucleon and four-nucleon systems. Based on these results, we discuss the implications for primordial abundances of light nuclei, the production of nuclei in stellar environments, and implications for an anthropic view of the universe.

  1. RadioAxion results on the search for axion dark matter under Gran Sasso

    hep-ex 2026-02 unverdicted novelty 7.0 of 10

    The RadioAxion experiment at Gran Sasso found no evidence for axion dark matter induced periodic modulations in 241Am decays and derived constraints on the axion decay constant for masses from 10^{-21} to 10^{-9} eV.

  2. Baryoid Dark Matter from $\mathbb{Z}_N$ Domain Walls: The $(N-1):1$ origin of the dark matter-baryon coincidence

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    Collapsing Z_N domain walls trap baryons into dense baryoids, yielding a dark matter-baryon energy density ratio of approximately (N-1):1 after the QCD phase transition.

  3. Weak nuclear decays deep-underground as a probe of axion dark matter

    hep-ph 2024-12 unverdicted novelty 6.0 of 10

    A framework is developed to predict axion-induced time modulations in weak nuclear decays, used to derive constraints on the axion decay constant from reanalyzed Gran Sasso data on 40K and 137Cs and to propose future ...

  4. Constraint on ultralight Nelson-Barr dark matter from time-dependent nuclear decay

    hep-ph 2025-06 conditional novelty 4.0 of 10

    Non-observation of periodic modulation in tritium beta decay sets a new 95% CL exclusion on ultralight Nelson-Barr scalar dark matter: f below 7.0e9 to 1.4e7 GeV is ruled out for m_phi in 3.4e-23 to 1.7e-20 eV.
