Query: Gauged $U(1)$ Clockwork   We review the gauged $U(1)$ clockwork models as portals for new physics to
obtain effectively hierarchical couplings of the Standard Model (SM) particles
from genuine couplings of order one. Nearest-neighbor mass mixing between
multiple $U(1)$ gauge bosons lead to the localization of the zero mode gauge
boson, realizing the milicharged gauge boson in the effective theory. We
discuss some of interesting examples utilizing the gauged clockwork beyond the
SM.
