Abstract

We propose a simple model in which MSSM plus neutrino mass term, $(LH_u)^2$
is supplemented by a minimal flaton sector to drive the thermal inflation,
and make two crucial assumptions:
the flaton vacuum expection value generates the $\mu$-term of the MSSM and
$m_L^2 +m_{H_u}^2<0$.
We show that our model leads to thermal inflation followed by Affleck-Dine
leptogenesis along the $LH_u$ flat direction.
