Suppressed neutrino oscillations and large lepton asymmetries
A. D. Dolgov, Fuminobu Takahashi
It is shown that hypothetical neutrino-majoron coupling can suppress neutrino flavor oscillations in the early universe, in contrast to the usual weak interaction case. This reopen…

D-term Instability in Flat Directions and its Cosmological Implication
Masahiro Kawasaki, Fuminobu Takahashi
We study dynamics of flat directions in the minimal supersymmetric standard model taking account of its constituent fields. It is found that there exist new instabilities due to th…
