Query: Dynamical Clockwork Axions   The clockwork mechanism is a novel method for generating a large separation
between the dynamical scale and interaction scale of a theory. We demonstrate
how the mechanism can arise from a sequence of strongly-coupled sectors. This
framework avoids elementary scalar fields as well as ad hoc continuous global
symmetries, both of which are subject to serious stability issues. The
clockwork factor, $q$, is determined by the consistency of the strong dynamics.
The preserved global $U(1)$ of the clockwork appears as an accidental symmetry,
resulting from discrete or $U(1)$ gauge symmetries, and it is spontaneously
broken by the chiral condensates. We apply such a dynamical clockwork to
construct models with an effectively invisible QCD axion from TeV-scale strong
dynamics. The axion couplings are determined by the localisation of the
Standard Model interactions along the clockwork sequence. The TeV spectrum
includes either coloured hadrons or vector-like quarks. Dark matter can be
accounted for by the axion or the lightest neutral baryons, which are
accidentally stable.
