Warm Inflation in the light of Swampland Criteria

TL;DR

This paper examines how Warm Inflation models align with recent Swampland Criteria, showing they can satisfy both observational data and theoretical constraints in different dissipative regimes based on the potential slope parameter.

Contribution

It analyzes the compatibility of Warm Inflation with Swampland Criteria, highlighting parameter conditions under which the models are consistent with observations and theoretical limits.

Findings

Warm Inflation can satisfy Swampland Criteria in weak and strong dissipative regimes.

Compatibility depends on the value of the parameter c controlling the potential slope.

Models remain consistent with cosmological observations under certain parameter choices.

Abstract

Warm Inflation seems to be the most befitting single-field slow-roll inflation scenario in the context of the recently proposed Swampland Criteria. We investigate the constraints these Swampland Criteria impose on Warm Inflation parameters and show that Warm Inflation is in accordance with both the current cosmological observations and the proposed Swampland Criteria in both weak and strong dissipative regimes depending on the value of the parameter $c$ which limits the slope of the inflaton potential according to the criteria.
