Affleck-Dine inflation in supergravity

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Shusuke Ueda, , , | Summary: Affleck-Dine inflation is a recently proposed model in which a single complex scalar field, nonminimally coupled to gravity, drives inflation and simultaneously generates the baryon asymmetry of universe via Affleck-Dine mechanism. In this paper we investigate the supersymmetric implementation […]

Three-flavor collective neutrino conversions with multi-azimuthal-angle instability in an electron-capture supernova model

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Masamichi Zaizen, Shunsaku Horiuchi, Tomoya Takiwaki, Kei Kotake, Takashi Yoshida | Summary: We investigate the multi-azimuthal angle (MAA) effect on collective neutrino oscillation by considering the three-dimensional neutrino momentum distribution in a realistic electron-capture supernova model with an $8.8 M_{odot}$ progenitor. We find that the MAA effect […]
