Direct baryogenesis in the broken phase
Takehiko Asaka, Hiroyuki Ishida, Wen Yin
We show a new mechanism for baryogenesis where the reheating temperature can be smaller than the electroweak scale. The baryon number symmetry is violated by a dimension nine opera…
Opening the 1Hz axion window
David J. E. Marsh, Wen Yin
An axion-like particle (ALP) with mass eV oscillates with frequency 1 Hz. This mass scale lies in an open window of astrophysical constraints, and appears n…
Throwing away antimatter via neutrino oscillations during the reheating era
Shintaro Eijima, Ryuichiro Kitano, Wen Yin
The simplest possibility to explain the baryon asymmetry of the Universe is to assume that radiation is created asymmetrically between baryons and anti-baryons after the inflation.…
QCD Axion on Hilltop by a Phase Shift of
Fuminobu Takahashi, Wen Yin
We show that the initial misalignment angle of the QCD axion (or axion-like particles) can be set very close to , if the QCD axion has a mixing with another heavy axion which in…
Bino-wino coannihilation as a prediction in the unification of families
Tsutomu T. Yanagida, Wen Yin, Norimi Yokozaki
We study the phenomenological consequences of the supersymmetric (SUSY) non-linear sigma model coupled to supergravity, where the three generations of quar…
Explaining electron and muon anomaly in SUSY without lepton-flavor mixings
Motoi Endo, Wen Yin
We propose a SUSY scenario to explain the current electron and muon discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can…
ALP inflation and Big Bang on Earth
Fuminobu Takahashi, Wen Yin
We study a hilltop inflation model where an axion-like particle (ALP) plays the role of the inflaton. We find that, for a broad class of potentials, the decay constant and the mass…
Relaxing the Cosmological Moduli Problem by Low-scale Inflation
Shu-Yu Ho, Fuminobu Takahashi, Wen Yin
We show that the cosmological abundance of string axions is much smaller than naive estimates if the Hubble scale of inflation, , is sufficiently low (but can still be…
