Abstract

Affleck-Dine leptogenesis after thermal inflation along the LHuLH_u direction requires mL2+mHu2<0m_L^2+m_{H_u}^2 < 0 up to the AD scale (LHu109|L|\simeq |H_u|\sim 10^9 GeV). We renormalised this condition from the AD scale to the soft supersymmetry breaking scale by solving the renormalisation group equations perturbatively in the Yukawa couplings to obtain a semi-analytic constraint on the soft supersymmetry breaking parameters. We also used a fully numerical method to renormalise the baryogenesis condition and constrained the Minimal Supersymmetric Cosmological Model using the resulting baryogenesis condition and other constraints, specifically, electroweak symmetry breaking, the observed Higgs mass, and the axino dark matter abundance.
