Imperfect Axion Precludes the Domain Wall Problem
Yue Zhang
The QCD axion needs not be an exact pseudoscalar for solving the strong CP problem. Its imperfectness can play a profound role cosmologically. We propose effective operators, where…
Can Neutrino Self-interactions Save Sterile Neutrino Dark Matter?
Rui An, Vera Gluscevic, Ethan O. Nadler +1
Sterile neutrinos only interact with the Standard Model through the neutrino sector, and thus represent a simple dark matter (DM) candidate with many potential astrophysical and co…
The Axion Quality and Fifth Force
Yue Zhang
We investigate what it takes for the axion to address the strong CP problem in the presence of explicit Peccei-Quinn (PQ) symmetry breaking effects besides the strong interaction.…
Core-collapse Supernova Constraint on the Origin of Sterile Neutrino Dark Matter via Neutrino Self-interactions
Yu-Ming Chen, Manibrata Sen, Walter Tangarife +2
Novel neutrino self-interaction can open up viable parameter space for the relic abundance of sterile-neutrino dark matter (SDM). In this work, we constrain the relic target usi…
Dark Matter Dilution Mechanism through the Lens of Large Scale Structure
Miha Nemevšek, Yue Zhang
Entropy production is a necessary ingredient for addressing the over-population of thermal relics. It is widely employed in particle physics models for explaining the origin of dar…
Neutrino Self-Interactions: A White Paper
Jeffrey M. Berryman, Nikita Blinov, Vedran Brdar +31
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known…
