Cosmological implications of in light of the Hubble tension
Fuminobu Takahashi, Wen Yin
Recently, a low- measurement of the Hubble constant, , was reported by the SH0ES Team. The long-standing Hubble tension, i.e. the differenc…
Phenomenology of CP-even ALP
Kodai Sakurai, Wen Yin
Axion or axion-like particle (ALP) has been usually considered as a CP-odd Nambu-Goldstone boson (NGB) from the spontaneous breakdown of a global U(1) symmetry. In this paper, we p…
Shining ALP Dark Radiation
Joerg Jaeckel, Wen Yin
String scenarios typically not only predict axion-like particles (ALPs) but also significant amounts of ALP dark radiation originating from the decay of the inflaton or a more gene…
Small cosmological constant from a peculiar inflaton potential
Wen Yin
We propose a novel scenario to explain the small cosmological constant (CC) by a finely tuned inflaton potential. The tuned shape is stable under radiative corrections, and our set…
Baryogenesis via relativistic bubble walls
Aleksandr Azatov, Miguel Vanvlasselaer, Wen Yin
We present a novel mechanism which leads to the baryon asymmetry generation during the strong first order phase transition. If the bubble wall propagates with ultra-relativistic ve…
Hidden Photon and Axion Dark Matter from Symmetry Breaking
Kazunori Nakayama, Wen Yin
A light hidden photon or axion-like particle is a good dark matter candidate and they are often associated with the spontaneous breaking of dark global or gauged U(1) symmetry. We…
