Description
We consider a partially composite axion which results from a linear mixing between an elementary scalar and a composite operator of dimension four. Non-perturbative effects generate a mass for the partially composite axion and mix it with the heavier axion states. This causes the misalignment mechanism to produce multiple axions with different abundances and leads to new interesting phenomenology in dynamical dark matter models.
