Cosmological axion and neutrino mass constraints from Planck 2015 temperature and polarization data
Axions currently provide the most compelling solution to the strong CP problem. These particles may be copiously produced in the early universe, including via thermal processes. Therefore, relic axions constitute a hot dark matter component and their masses are strongly degenerate with those of the...
