  I briefly discuss the main phenomenological features and constraints of the
Clockwork/Linear Dilaton (CW/LD) 5D geometry. This contribution is based on the
work of ref. arXiv:1711.08437, to which the reader is referred for an extensive
discussion of the subject and the full list of relevant references. The only
original result of this proceeding is adding the constraint arising from the
CMS analysis CMS-PAS-EXO-17-017 to the summary plot.
