The minimal flavour violating axion and its effect on $\Delta N_{eff}$
We study a possible solution to the Strong CP Problem in the Minimal FlavourViolation (MFV) framework. An Abelian factor of the complete flavour symmetry ofthe fermionic kinetic terms is identified as the Peccei-Quinn symmetry intraditional axion models. Its spontaneous breaking generates the MFV ax...
