/ Abstract
A very weakly coupled scalar field with mass $m$ and initial vacuum expectation value $V$ will provide enough mass to close the Universe provided $V\ensuremath{\simeq}(3\ifmmode\times\else\texttimes\fi{}{10}^{8}\mathrm{GeV}){(100 \frac{\mathrm{GeV}}{m})}^{\frac{1}{4}}$. We discuss possible models in which such a field could arise.
