DESCRIPTION:The masses of the SM fermions span many orders of magnitude. W
 hile technically natural\, this spread and the pattern of masses and mixin
 gs beg for a deeper theoretical explanation. Many mechanisms to solve this
  flavour problem have been proposed\, like Froggatt-Nielsen\, partial comp
 ositeness\, discrete symmetries etc. These mechanisms have in common that 
 a given model realization is defined by a huge number of theory parameters
 \, from the choice of representation to many possible coefficients or stat
 es in a given model's UV completion. This motivates a systematic approach 
 to achieve a bird's-eye-view of a given mechanism and its potentially test
 able predictions at current or future experiments. In two recent papers (2
 306.08026\, 2501.00629)\, we define such an approach and apply it to the F
 roggatt-Nielsen (FN) mechanism in the quark and lepton sectors respectivel
 y. This global view of FN yields several new phenomenological insights\, c
 an be readily applied to other flavour mechanisms\, and facilitates enquir
 ies into the deeper connections between flavour and other questions like t
 he nature of dark matter or the hierarchy problem.\n\nhttps://indico.bnl.g
