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…
Testable Inverse Seesaw Motivated from a High Quality QCD Axion
Yannis Georis, Jie Sheng, Salvador Urrea +1
The QCD axion remains one of the most compelling solutions to the strong CP problem. Meanwhile, the type-I seesaw mechanism offers an elegant explanation for the lightness of the o…
Testing Electromagnetic Memory via Acceleration-Induced Phase Imprints in Superconductors
Jie Sheng, Tsutomu T. Yanagida, Bo Gao +1
Electromagnetic memory is an infrared observable of gauge theory associated with soft photons and large gauge transformations. Despite its fundamental theoretical importance, it ha…
High Quality QCD Axion in the Standard Model
Jie Sheng, Tsutomu T. Yanagida
Although the axion is the most compelling solution to the strong CP problem, the ad hoc introduced global Peccei-Quinn symmetry suffers from a severe fine-tuning problem known as t…
Superconducting Cloud Chamber
Bo Gao, Jie Sheng, Tsutomu T. Yanagida
We propose a new particle-trajectory detector composed of Josephson junctions, named the superconducting cloud chamber. By measuring the quantum phase difference, this device can d…
Féeton ( Gauge Boson) Dark Matter Testable in Future Direct Detection Experiments
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
In this paper, we revisit the féeton (gauge boson of symmetry) dark matter scenario, and first point out the gauge symmetry can be a linear combination of the $…
Proposal for a Quantum Mechanical Test of Gravity at Millimeter Scale
Yu Cheng, Jiadu Lin, Jie Sheng +1
The experimental verification of the Newton law of gravity at small scales has been a longstanding challenge. Recently, torsion balance experiments have successfully measured gravi…
Detecting a Fifth-Force Gauge Boson via Superconducting Josephson Junctions
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
A new fifth force between particles carrying charges is well-motivated by the intriguing extension of the standard model. The gauge boson mediator, Féeton, also…
Thermal Relic Right-Handed Neutrino Dark Matter
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
It is known that two heavy Majorana right-handed neutrinos are sufficient to generate the baryon asymmetry in the present universe. Thus, it is interesting to identify the third ri…
Ultraheavy Atomic Dark Matter Freeze-Out through Rearrangement
Yu-Cheng Qiu, Jie Sheng, Liang Tan +1
Atomic dark matter is usually considered to be produced asymmetrically in the early Universe. In this work, we first propose that the symmetric atomic dark matter can be thermally…
Féeton ( Gauge Boson) Dark Matter for the 511-keV Gamma-Ray Excess and the Prediction of Low-energy Neutrino Flux
Yu Cheng, Weikang Lin, Jie Sheng +1
The féeton is the gauge boson of the gauge theory. If the gauge coupling constant is extremely small, it becomes a candidate for dark matter. We show that its decay to…
