abstract

We study cosmological constraints on dark pure Yang-Mills sectors. Dark glueballs are overproduced for large regions of ultraviolet parameter space. The problem may be alleviated in two ways: via a large preferential reheating into the visible sector, motivating certain inflation or modulus decay models, or via decays into axions or moduli, which are strongly constrained by nucleosynthesis and $\Delta N_{\text{eff}}$ bounds. String models frequently have multiple hidden Yang-Mills sectors, which are subject to even stronger constraints due to the existence of multiple dark glueballs.

  1. Fuzzy Axions and Associated Relics

    hep-th 2024-12 conditional novelty 8.0 of 10

    In explicit string theory compactifications, fuzzy axion dark matter is rare and typically requires fine-tuning of initial axion displacements or a non-standard reheating epoch to avoid overproducing heavier axions.

  2. Dark Monopoles, Bounds on Hidden Sectors, and Cosmological Implications

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Hidden-sector magnetic monopoles with symmetry-breaking scales above roughly 100 PeV over-close the Universe unless diluted by inflation or an early matter-dominated phase.

  3. The String Theory Photoverse

    hep-th 2025-10 conditional novelty 6.0 of 10

    Massless string-theory hidden photons acquire dimension-six dipole couplings to SM fermions with suppression scale Λ = αM_s, converting dipole measurements into constraints on the string scale.

  4. Rich Phenomenology from Simple Ingredients: A Review of Confining Dark Sectors

    hep-ph 2026-06 unverdicted novelty 2.0 of 10

    Review of confining dark sectors summarizing dark matter candidates, abundance mechanisms, discovery channels, and applications to the abundance similarity puzzle.

  5. Dark Horse, Dark Matter: Revisiting the SO(16)x SO(16)' Nonsupersymmetric Model in the LHC and Dark Energy Era

    hep-th 2019-07 unverdicted novelty 2.0 of 10

    Reexamination of the SO(16)xSO(16)' nonsupersymmetric model for implications on dark energy, vacuum stabilization, dark matter candidates, and gauge-Higgs unification in light of LHC and dark energy data.
