Description
The talk will be about CP violation but also about axion shift-invariance breaking. In both cases, Jarlskog-like flavour invariants capture collective breaking effects and allow one to define parameters orders that measure the amount of symmetry breaking and that could be used to define a self-consistent power counting closed under the renormalisation group evolution.
