Scalars Gliding Through an Expanding Universe
Anson Hook, Gustavo Marques-Tavares, Yuhsin Tsai
In this article we investigate the effects of single derivative mixing in massive bosonic fields. In the regime of large mixing, we show that this leads to striking changes of the…
A CMB Millikan Experiment with Cosmic Axiverse Strings
Prateek Agrawal, Anson Hook, Junwu Huang
We study axion strings of hyperlight axions coupled to photons. Hyperlight axions -- axions lighter than Hubble at recombination -- are a generic prediction of the string axiverse.…
Ultralight dark matter detection with mechanical quantum sensors
Daniel Carney, Anson Hook, Zhen Liu +2
We consider the use of quantum-limited mechanical force sensors to detect ultralight (sub-meV) dark matter candidates which are weakly coupled to the standard model. We show that m…
Minimal signatures of the Standard Model in non-Gaussianities
Anson Hook, Junwu Huang, Davide Racco
We show that the leading coupling between a shift symmetric inflaton and the Standard Model fermions leads to an induced electroweak symmetry breaking due to particle production du…
Searches for other vacua II: A new Higgstory at the cosmological collider
Anson Hook, Junwu Huang, Davide Racco
The detection of an oscillating pattern in the bispectrum of density perturbations could suggest the existence of a high-energy second minimum in the Higgs potential. If the Higgs…
Naturalness without new particles
Anson Hook
We demonstrate that the physics which resolves naturalness problems need not take the form of new particles and can sometimes manifest itself as higher dimensional operators. As a…
