Description
We introduce a set of clockwork models of flavor that can naturally
explain the large hierarchies of the Standard Model quark masses and
mixing angles. Since the clockwork only contains chains of new
vector-like fermions without any other dynamical fields, the flavor
constraints allow for relatively light new physics scale. For two
benchmarks with gear masses just above 1 TeV, allowed by flavor
constraints, we discuss the collider searches and the possible ways of
reconstructing gear spectra at the LHC. We also examine the similarities
and differences with the other common solutions to the SM flavor puzzle,
i.e., with the Froggatt-Nielsen models, where we identify a new
clockworked version, and with the Randall-Sundrum models.
