  The next generation of experiments in particle physics will for the first
time systematically test flavor physics models based on flavon fields. Starting
from the current quark-flavor constrains on such models we show how the new
generation of lepton flavor experiments will dominate indirect searches in the
coming decades. A future 100 TeV hadron collider will then be the first
experiment to probe flavons as propagating degrees of freedom. Our estimate of
the collider reach relies on a proper treatment of backgrounds and detector
effects. Complementary searches for indirect effects in lepton flavor
experiments and propagating degrees of freedom at colliders are very limited at
the LHC, but will be a new feature at a 100 TeV hadron collider.
