The clockwork mechanism, which can naturally explain the origin of small numbers, is
implemented in SO (10) grand unified theories to address the origin of hierarchies in fermion …

A bstract We consider various bulk fields with general dilaton couplings in the linear dilaton
background in five dimensions as the continuum limit of clockwork models. We show that the …

A bstract We develop a new class of clockwork theories with an augmented structure of the
near-neighbour interactions along a one-dimensional closed chain. Such a topology leads …

The clockwork mechanism provides a natural way to obtain hierarchical masses and
couplings in a theory. We propose a clockwork model that has nine clockwork generations …

The conventional ultralight QCD axion is typically rendered invisible at collider experiments
by its large decay constant. What could also hint at its possible existence is the observation …

We present realistic models of flavor in SU (5) and SO (10) grand unified theories (GUTs).
The models are renormalizable and do not require any exotic representations in order to …

A bstract We propose a simple clockwork model of flavor which successfully generates the
Standard Model flavor hierarchies from random order-one couplings. With very few …

In this paper, we have looked at various variants of the clockwork model and studied their
impact on the neutrino masses. Some of the generalizations such as generalized CW and …

Maybe the biggest puzzle in grand unified theories (GUTs) is the apparent large splitting of
the doublet and triplet Higgs masses. We suggest a novel mechanism to solve this puzzle …

A bstract Compactifications of heterotic M-theory are shown to provide solutions to the weak-
and axion-scale hierarchy problems as a consequence of warped large extra dimensions …
