Solving the Hierarchy Problem Discretely
read the original abstract
We present a new solution to the Hierarchy Problem utilizing non-linearly realized discrete symmetries. The cancelations occur due to a discrete symmetry that is realized as a shift symmetry on the scalar and as an exchange symmetry on the particles with which the scalar interacts. We show how this mechanism can be used to solve the Little Hierarchy Problem as well as give rise to light axions.

Weak nuclear decays deep-underground as a probe of axion dark matter
A framework is developed to predict axion-induced time modulations in weak nuclear decays, used to derive constraints on the axion decay constant from reanalyzed Gran Sasso data on 40K and 137Cs and to propose future ...

Counting axions with IAXO
Projections for IAXO in two-axion parameter space plus spectral analysis of flavor oscillations show where the experiment can discriminate multi-axion signals from single-axion ones, extending to N-axion cases.
