Distance, de Sitter and Trans-Planckian Censorship conjectures: the status quo of Warm Inflation

TL;DR

This paper discusses how warm inflation remains favored over cold inflation under recent conjectures that challenge de Sitter constructions, highlighting the compatibility of warm inflation with both the de Sitter and trans-Planckian censorship conjectures.

Contribution

It analyzes the status of warm inflation in light of recent conjectures, showing its compatibility and contrasting it with cold inflation models that fail both conjectures.

Findings

Warm inflation remains favored under the conjectures.

Cold inflation models are increasingly unlikely due to the conjectures.

Warm inflation can satisfy both the de Sitter and trans-Planckian censorship conjectures.

Abstract

In this short note, we pointed out that Warm inflationary scenario remains to be favoured over its cold counterpart by the recently proposed conjectures, which aim to overrule de Sitter like constructions in String Landscapes. On the other hand, the canonical cold (single-field slow-roll) inflationary models, which were in tension with the previously proposed de Sitter conjecture, have now become even more unlikely to realise in String Landscapes as these scenarios fail to cope up with both the conjectures, de Sitter and trans-Planckian censorship, at one go.
