- | <note tip> | + | The flavor puzzle is the question why do the particles in the [[models:standard_model|standard model of particle physics]] have the values they have, and why do the mixing angles in the PMNS and CKM matrix have the values they have. |
- | Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. | + | |
