A Natural Dark Matter-Dark Energy Interaction from Axion-Monopole Dynamics
Hengameh Bagherian, Matthew Reece, Lian-Tao Wang +1
We propose a natural framework for interacting dark matter and dark energy based on axion-monopole dynamics in a dark gauge sector. Dark matter is composed of dark 't Hooft-Polyako…
Higgsino Above the Sea of Fog
JiJi Fan, Matthew Reece
Higgsino dark matter is a classic, but still viable, weakly-interacting massive particle (WIMP) scenario that could point to supersymmetry, a new spacetime symmetry of nature. It i…
Axion Perturbations: A General Analytical Treatment
Itamar J. Allali, Priyesh Chakraborty, JiJi Fan +1
Cosmological data provides us two key constraints on dark matter (DM): it must have a particular abundance, and it must have an adiabatic spectrum of density perturbations in the e…
A Step in Flux to Suppress Axion Isocurvature
Priyesh Chakraborty, Junyi Cheng, Matthew Reece +1
The QCD axion in the pre-inflation scenario faces a stringent isocurvature constraint, which requires a relatively low Hubble scale during inflation. If the axion was heavier than…
Extra-Dimensional Axion Expectations
Matthew Reece
Axions arising as modes of higher-dimensional gauge fields are known to offer a compelling solution to the axion quality problem and to naturally arise in string theory. In this co…
The Quality/Cosmology Tension for a Post-Inflation QCD Axion
Qianshu Lu, Matthew Reece, Zhiquan Sun
It is difficult to construct a post-inflation QCD axion model that solves the axion quality problem (and hence the Strong CP problem) without introducing a cosmological disaster. I…
