Some open questions in axion theory

High Energy Physics - Phenomenology 2022-03-16 v1 High Energy Physics - Theory

Abstract

This white paper collects some open questions in several different aspects of axion theories. The questions are related to quantization of axion couplings, axion-magnetic monopole systems, axions in quantum gravity theory, axion string/domain wall systems, and thermal friction from axion couplings. They demonstrate many opportunities for axion theory, which call for more studies.
