  Late-decaying string moduli dilute the baryon asymmetry of the universe
created in any previous era. The reheat temperature for such moduli is below a
GeV, thus motivating baryogenesis at very low temperatures. We present an
extension of the minimal supersymmetric standard model with TeV-scale colored
fields that can yield the correct baryon asymmetry of the universe in this
context. Modulus decay, which reheats the universe at a temperature below GeV,
produces the visible sector fields and neutralino dark matter in non-thermal
fashion. We discuss various possibilities for baryogenesis from TeV scale
colored fields and show that they can generate an acceptable baryon asymmetry,
while being compatible with phenomenological constraints like
neutron-antineutron oscillation.
