Content
We have investigated the Affleck-Dine baryogenesis in detail and have shown that the baryon-dark matter coincidence problem can be solved in the mSUGRA/CMSSM model with a 126 GeV Higgs boson. The baryons and dark matter are generated simultaneously through the late-time decay of non-topological solitons, Q-balls, which are formed after the Affleck-Dine baryogenesis. A relation between the universal scalar mass and the unified gaugino mass is required to solve the coincidence problem, marginally depending on the other mSUGRA parameters.
