Cosmic Clues: DESI, Dark Energy, and the Cosmological Constant Problem
Wen Yin
Several attempts to solve the cosmological constant problem, which concerns the value of the cosmological constant being extremely smaller than the Standard Model mass scales, have…
Bubble Misalignment Mechanism for Axions
Junseok Lee, Kai Murai, Fuminobu Takahashi +1
We study the dynamics of axions at first-order phase transitions in non-Abelian gauge theories. When the duration of the phase transition is short compared to the timescale of the…
QCD Axion Hybrid Inflation
Yuma Narita, Fuminobu Takahashi, Wen Yin
When the inflaton is coupled to the gluon Chern-Simons term for successful reheating, mixing between the inflaton and the QCD axion is generally expected given the solution of the…
Role of QCD in moduli stabilization during inflation and axion dark matter
Ryuichiro Kitano, Motoo Suzuki, Wen Yin
Ignorance of the initial condition for the axion dynamics in the early Universe has led us to consider an valued initial amplitude, and that prefers the decay constant, $F_a…
Indirect Detection of Decaying Dark Matter with High Angular Resolution: Case for axion search by IRCS at Subaru Telescope
Wen Yin, Kohei Hayashi
Recent advances in cosmic-ray detectors have provided exceptional sensitivities of dark matter with high angular resolution. Motivated by this, we present a comprehensive study of…
Thermal production of cold "hot dark matter" around eV
Wen Yin
A very simple production mechanism of feebly interacting dark matter (DM) that rarely annihilates is thermal production, which predicts the DM mass around eV. This has been widely…
