We consider the minimally coupled 3-form field which has been considered as a candidate to realize inflation. We have studied the conditions to avoid ghosts and Laplacian instabilities and found that some classes of potentials, e.g. the Mexican-hat one, will in general be unstable. We then propose other classes of potentials which are instead free from any instability, drive a long-enough slow-roll regime followed by an oscillatory epoch, and as a consequence, can provide successful inflation. Finally, we also provide stable potentials which lead to a small enough propagation speed for the scalar perturbations, giving a possibility for these models to produce non-Gaussianities.

  1. Black Bounce Solutions from a Self-Interacting 3-Form Field in General Relativity

    gr-qc 2026-06 unverdicted novelty 6.0

    Black-bounce solutions are obtained from a self-interacting 3-form field in GR plus scalar, producing two families that are globally regular with asymmetric horizons and different scalar behaviors.

  2. Three-form dark energy: constraints and multi-probe comparison with $\Lambda$CDM

    astro-ph.CO 2026-06 unverdicted novelty 4.0

    Three-form dark energy with Gaussian potential is fitted to multi-probe cosmological data and shows mild statistical preference over ΛCDM only in heavily tensioned dataset combinations.
