Query: The Minimal Flavour Violating Axion   The solution to the Strong CP problem is analysed within the Minimal Flavour
Violation (MFV) context. An Abelian factor of the complete flavour symmetry of
the fermionic kinetic terms may play the role of the Peccei-Quinn symmetry in
traditional axion models. Its spontaneous breaking, due to the addition of a
complex scalar field to the Standard Model scalar spectrum, generates the MFV
axion, which may redefine away the QCD theta parameter. It differs from the
traditional QCD axion for its couplings that are governed by the fermion
charges under the axial Abelian symmetry. It is also distinct from the
so-called Axiflavon, as the MFV axion does not describe flavour violation,
while it does induce flavour non-universality effects. The MFV axion
phenomenology is discussed considering astrophysical, collider and flavour
data.
