Affleck-Dine baryogenesis after thermal inflation

We argue that an extension of the minimal supersymmetric standard model (MSSM) that gives rise to viable thermal inflation, and so does not suffer from a Polonyi or moduli problem, should contain right-handed neutrinos which acquire their masses due to the vacuum expectation value of the flaton that drives thermal inflation. This strongly disfavors SO(10) grand unified theories. The μ term of the MSSM should also arise due to the VEV of the flaton. With the extra assumption that mL²-m_Hᵤ²<0, but, of course, mL²-m_Hᵤ²+|μ|²>0, we show that a complicated Affleck-Dine-type baryogenesis employing an LHᵤ D-flat direction can naturally generate the baryon asymmetry of the Universe.
