Description
A continuum limit of the clockwork mechanism provides a useful picture to understand extra dimensions. The Generalized Linear Dilaton model (GLD) realizes the continuum clockwork with varying clockwork gear masses. A special point of GLD is the linear dilaton model (LD) which has been discussed from the type II little string theory. In this talk, I will discuss a possible UV completion of GLD from different types of string theory. It will be shown that the Horava-Witten theory (or Heterotic M-theory) provides a direct realization of certain types of GLD with characteristic phenomenological features. Furthermore, I will discuss the possibility that more general M-theory limit via 11D supergravity can realize LD and Randall-Sundrum (RS) points.
