In the framework where the strong coupling is dynamical, the QCD sector may confine at a much higher temperature than it would in the Standard Model, and the temperature-dependent mass of the QCD axion evolves in a non-trivial way. We find that, depe... Read More about Resurrecting low-mass axion dark matter via a dynamical QCD scale.
