Baryogenesis, Dark Matter and the Maximal Temperature of the Early
  Universe
  Mechanisms for the generation of the matter-antimatter asymmetry and dark
matter strongly depend on the reheating temperature T_R, the maximal
temperature reached in the early universe. Forthcoming results from the LHC,
low energy experiments, astrophysical observations and the Planck satellite
will significantly constrain baryogenesis and the nature of dark matter, and
thereby provide valuable information about the very early hot universe. At
present, a wide range of reheating temperatures is still consistent with
observations. We illustrate possible origins of matter and dark matter with
four examples: moduli decay, electroweak baryogenesis, leptogenesis in the
nuMSM and thermal leptogenesis. Finally, we discuss the connection between
baryogenesis, dark matter and inflation in the context of supersymmetric
spontaneous B-L breaking.
