Query: Dark origin of quark flavor hierarchy and mixing   We provide a dynamical mechanism for the generation of the
Cabibbo-Kobayashi-Maskawa matrix in the context of a recently proposed model of
flavor. The framework, based on the paradigm that Yukawa couplings are
effective low energy couplings generated radiatively by dark sector
interactions, is here extended to include a new scalar field which plays the
role of a {\it dark flavon}. Being singlet under the Standard Model gauge group
but charged under the $U(1)$ symmetry of the dark sector, this particle sources
new two- and three-loop diagrams that result in off-diagonal Yukawa
interactions, thereby providing a simple explanation for the observed structure
of the CKM matrix. By using an effective parametrization of these new loop
contributions, we show that the CKM matrix elements can be correctly reproduced
for perturbative values of the involved couplings. We outline the rich
phenomenology predicted by the scenario and detail its implications for the LHC
and future collider experiments.
