On the realization of the MSSM inflation (2009)
We study the fine-tuning problem on the initial condition of inflation in the minimal supersymmetric standard model (MSSM), associated with the narrowness of the slow-roll region. We consider two...
Affleck Dine leptogenesis via multiple flat directions (2008)
Kamada, Kohei, Yokoyama, Jun'ichi
We investigate the Affleck-Dine mechanism when multiple flat directions have large values simultaneously. We consider in detail the case when both $LH_u$ and $H_uH_d$ flat directions are operative...
