Interacting Dark Energy and Dark Matter in O(3) No-Scale Gravity
Lincoln da S. Pereira, Muzi Hong, Elisa G. M. Ferreira +1
Dark Energy (DE) and Dark Matter (DM) are among the greatest mysteries in particle physics and cosmology, since their origins remain unclear. It is intriguing to consider whether b…
Minimal Majoron Dark Matter from a Discrete Gauge Symmetry
Subaru Fujisawa, Qiuyue Liang, Shigeki Matsumoto +2
We investigate majoron dark matter in a minimal setup, where the Standard Model is extended by three right-handed neutrinos and a complex scalar field. The theory is defined by an…
Probing Majoron Dark Matter with Gravitational Wave Detectors
Ippei Obata, Tsutomu T. Yanagida
The Majoron is a hypothetical (pseudo) Nambu-Goldstone boson arising from the spontaneous breaking of a global lepton number symmetry, and is known as a candidate for dark matter i…
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…
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…
