# Quantum corrections to vacuum energy sequestering (with monodromy)

## TL;DR

This paper investigates quantum loop corrections in axion monodromy models of vacuum energy sequestering, showing that while the original structure is altered at low energies, the cancellation of radiative corrections remains effective.

## Contribution

It provides a detailed analysis of one-loop quantum corrections in axion monodromy models, demonstrating the robustness of vacuum energy sequestering against quantum effects.

## Key findings

- Original sequestering structure is modified at low energies.
- Cancellation of radiative corrections remains effective.
- Quantum corrections introduce new structures but do not compromise sequestering.

## Abstract

Field theory models of axion monodromy have been shown to exhibit vacuum energy sequestering as an emergent phenomenon for cancelling radiative corrections to the cosmological constant. We study one loop corrections to this class of models coming from virtual axions using a heat kernel expansion. We find that the structure of the original sequestering proposals is no longer preserved at low energies. Nevertheless, the cancellation of radiative corrections to the cosmological constant remains robust, even with the new structures required by quantum corrections.
