abstract

In this paper, we show that single-field chaotic inflation on the brane with the potential $V=a \phi^p$ is compatible with the Swampland criteria. The spectral index and the running spectral index are within experimental bounds for $0<p \leq 2$. The tensor to scalar ratio is within observational bounds if $p \lesssim \mathcal{O}(1)$.

Discussion (0). Continue with ORCID to comment.

  1. Helical phase inflation and its observational constraints

    hep-ph 2019-08 conditional novelty 5.0 of 10

    Helical phase inflation, using the phase of a complex scalar as the inflaton, fits Planck 2018 and BICEP2 data and is claimed to show alpha-attractor behavior, with a brane version that reduces field excursions.
