Revisiting the stochastic QCD axion window: departure from equilibrium during inflation
Vadim Briaud, Kenji Kadota, Shinji Mukohyama +2
If dark matter is made of QCD axions, its abundance is determined by the vacuum expectation value acquired by the axion field during inflation. The axion is usually assumed to foll…
