Charge non-conservation,dequantisation, and induced electric dipole moments in varying-α theories

We note that in extensions of the Standard Model that allow for a varying fine structure constant, α, all matter species, apart from right-handed neutrinos, will gain an intrinsic electric dipole moment (EDM). In a large subset of varying-α theories, all such particle species will also gain an effective electric charge. This charge will, in general, not be quantised and can result in macroscopic non-conservation of electric charge.
