From Swampland to Phenomenology and Back

TL;DR

This paper explores the relationship between swampland conjectures and phenomenology, highlighting how each informs and constrains the other in the quest for a consistent quantum gravity framework.

Contribution

It provides a conceptual analysis of how swampland conjectures impact phenomenological models and vice versa, advancing understanding of quantum gravity constraints.

Findings

Swampland conjectures impose significant constraints on low-energy effective theories.

Phenomenological considerations help refine and test swampland conjectures.

The interplay guides the search for viable quantum gravity theories.

Abstract

Swampland conjectures are a set of proposed necessary conditions for a low-energy effective field theory to have a UV completion inside a theory of quantum gravity. Swampland conjectures have interesting phenomenological consequences, and conversely phenomenological considerations are useful guidelines in sharping our understanding of quantum gravity.
