1. Flavon stabilization in models with discrete flavor symmetry / Chigusa, So ; Kasuya, Shinta ; Nakayama, Kazunori
We propose a simple mechanism for stabilizing flavon fields with aligned vacuum structure in models with discrete flavor symmetry. [...]

2. Axino dark matter and baryon number asymmetry production by the Q-ball decay in gauge mediation / Kasuya, Shinta ; Kawakami, Etsuko ; Kawasaki, Masahiro
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. [...]

3. IceCube potential for detecting Q -ball dark matter in gauge mediation / Kasuya, Shinta ; Kawasaki, Masahiro ; Yanagida, Tsutomu T.
We study $Q$ -ball dark matter in gauge-mediated supersymmetry breaking, and seek the possibility of detection in the IceCube experiment. [...]

4. Q -ball dark matter and baryogenesis in high-scale inflation / Kasuya, Shinta ; Kawasaki, Masahiro
We investigate the scenario that one flat direction creates baryon asymmetry of the universe, while Q balls from another direction can be the dark matter in the gauge-mediated supersymmetry breaking for high-scale inflation. [...]

5. Flat direction inflation with running kinetic term and baryogenesis / Kasuya, Shinta ; Takahashi, Fuminobu
We consider a possibility that one of the flat directions in the minimal supersymmetric standard model plays the role of the inflaton field and realizes large-field inflation. [...]
