Chaotic inflation on the brane and the Swampland Criteria

TL;DR

This paper demonstrates that single-field chaotic inflation models on the brane with specific potentials are compatible with Swampland criteria and observational data, especially for certain parameter ranges.

Contribution

It shows the compatibility of brane-world chaotic inflation models with Swampland criteria and observational constraints for specific potential parameters.

Findings

Spectral index and running within experimental bounds for 0<p≤2.

Tensor-to-scalar ratio within observational bounds for p≈O(1).

Models are consistent with Swampland criteria.

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 $p \lesssim \mathcal{O}(1)$.
