Formation of Supermassive Black Hole Seeds from Vacuum-Dependent Thermal Dark Matter
Masahiro Kawasaki, Jie Sheng, Tsutomu T. Yanagida
The origin of supermassive black holes, especially those already present at high redshift, remains an open problem. We propose that their seeds are primordial black holes formed fr…
The LUX-ZEPLIN Event as Hyperfine Spectroscopy of Composite Dark Matter
Jie Sheng, Kairui Zhang
We propose that the nuclear-recoil candidate reported by LUX--ZEPLIN can arise from the endothermic hyperfine excitation of composite dark matter. Rather than r…
High-Quality Axion Dark Matter without Isocurvature Problem
Masahiro Kawasaki, Jie Sheng, Tsutomu T. Yanagida
Axion dark matter in high-scale inflation is subject to the isocurvature constraint, since quantum fluctuations of the axion field during inflation may exceed the current CMB bound…
WIMP Dark Matter from a Natural Discrete Gauge Symmetry in the Standard Model
Jie Sheng, Tsutomu T. Yanagida, Kairui Zhang
The internal structure of the Standard Model implies a natural discrete gauge symmetry. Cancellation of the corresponding Dai--Freed anomalies re…
