In this work, we investigate the generation of primordial black holes (PBHs) within the framework of single-field inflationary models and their compatibility with the cosmological history of the Universe. Our results suggest that, depending on the masses of the formed PBHs, single-field inflation models require more than fine-tuning a potential to induce ultra-slow roll; it necessitates a comprehensive understanding of the post-inflationary cosmological evolution. As an explicative example, we introduce a new model, based on a double inflection point and consistent with Cosmic Microwave Background observations, capable of generating sub-solar PBHs, whose merger could be potentially detectable by the LVK experiment.

  1. ACT stands for Awkward Cosmology Theories

    hep-ph 2026-07 accept novelty 6.0 of 10

    Reconciling Starobinsky inflation with ACT data requires fine-tuned higher-curvature scales, stiff reheating with ω_reh>1/3, or negative-energy towers, all hard to motivate from UV completions.

  2. The Irrelevance of Primordial Black Hole Clustering in the LVK mass range

    astro-ph.CO 2025-02 accept novelty 6.0 of 10

    Initial spatial clustering of primordial black holes is irrelevant for binary mergers in the LVK mass range because FIRAS spectral-distortion constraints limit the clustering scale to below the merger-relevant separat...

  3. Are Primordial Black Holes Truly Fine-Tuned?

    astro-ph.CO 2025-12 conditional novelty 5.0 of 10

    Using a normalized sensitivity measure γ=c/c̄, the authors find γ≈1 for three single-field ultra-slow-roll inflation models and conclude PBH production is not technically unnatural.

  4. One-loop corrections to the E-type $\alpha$-attractor models of inflation and primordial black hole production

    gr-qc 2025-02 conditional novelty 5.0 of 10

    For E-type alpha-attractor inflation models tuned to produce asteroid-mass primordial black holes, the one-loop correction from cubic interactions is only a few percent of the tree-level power spectrum.
