Flavor Democracy
Why is it interesting?
Flavor democracy is one of the most attractive approaches to explain the observed mass and mixing angles pattern of the standard model.
It was already noted in 1978 that a Yukawa matrix where all entries are the same, i.e. democratic, yields one important aspect of the flavor puzzle automatically: the heaviness of the third generation. In addition, adding a small perturbation to this democratic ansatz yields successfull relations between the masses and mixing angles.
In addition, there is a close relationship to the (in)famous Koide formula and other popular solutions of the flavor problem, called Fritzsch textures.
