TASI Lectures on the Strong CP Problem and Axions
Anson Hook
These TASI lectures where given in 2018 and provide an introduction to the Strong CP problem and the axion. I start by introducing the Strong CP problem from both a classical and a…
Consequences of Fine-Tuning for Fifth Force Searches
Nikita Blinov, Sebastian A. R. Ellis, Anson Hook
Light bosonic fields mediate long range forces between objects. If these fields have self-interactions, i.e., non-quadratic terms in the potential, the experimental constraints on…
The Photophobic ALP
Nathaniel Craig, Anson Hook, Skyler Kasko
We explore models and phenomenology of a photophobic axion-like particle (ALP), an axion whose coupling to photons is maximally suppressed without fine-tuning of the underlying par…
Radio Signals from Axion Dark Matter Conversion in Neutron Star Magnetospheres
Anson Hook, Yonatan Kahn, Benjamin R. Safdi +1
We show that axion dark matter (DM) may be detectable through narrow radio lines emitted from neutron stars. The neutron star magnetosphere hosts a strong magnetic field and a plas…
Primordial Anisotropies in the Gravitational Wave Background from Cosmological Phase Transitions
Michael Geller, Anson Hook, Raman Sundrum +1
Phase transitions in the early universe can readily create an observable stochastic gravitational wave background. We show that such a background necessarily contains anisotropies…
Solving the Hierarchy Problem Discretely
Anson Hook
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 shif…
