We point out that a simple inflationary model in which the axionic inflaton couples to a pure Yang-Mills theory may give the scalar spectral index (n_s) and tensor-to-scalar ratio (r) in complete agreement with the current observational data.

  1. Dilaton-Flattened Axion Inflation

    hep-ph 2026-04 unverdicted novelty 7.0

    Dilaton backreaction on an anomaly-inspired axion potential generates a closed-form Lambert-W flattened hilltop, giving r ≈ 0.033–0.036 and α_s ≈ −4.6×10^{-4} at N=56 with strictly adiabatic dynamics.

  2. ACT-ing on inflation: Implications of non Bunch-Davies initial condition and reheating on single-field slow roll models

    astro-ph.CO 2025-05 unverdicted novelty 5.0

    Non-Bunch-Davies initial conditions substantially improve the fit of various single-field slow-roll inflation models to updated n_s-r constraints from ACT DR6 combined with Planck, DESI, and BICEP/Keck data.

  3. Pure Natural Inflation Passes the ACT

    astro-ph.CO 2026-03 unverdicted novelty 4.0

    Pure natural inflation remains viable against latest ACT+DESI constraints, with a non-trivial fraction of parameter space allowed under standard reheating scenarios.
