Sazžetak:


 I propose a massive antisymmetric tensor field as (cold) dark matter. This
 dark matter is produced by the amplification of vacuum fluctuation during an
 inflationary epoch in the early Universe. I find that the required mass of
 the antisymmetric field is of the order the neutrino masses (~0.03eV) for an
 inflationary theory at the grand unified scale. The energy peaks at a scale
 which corresponds roughly to the Earth-Sun distance today.
