Title:
The QCD Axion Mass

Speaker:
Malte Buschmann

Abstract:
If the axion is generated after inflation there is a unique mass that gives rise to the observed DM abundance; due to nonlinearities and topological defects known as axion strings, computing this mass accurately has been a challenge for four decades. Unfortunately, recent works have led to largely disparate predictions for the axion mass. I will go through some of the possible reasons for these discrepancies.
