The strangeness content of the nucleon

Abstract
We evaluate the matrix element of in hadron states on a lattice. We find substantial mixing of the connected and disconnected contributions so that the lattice result that the disconnected contribution to the nucleon is large does not imply that the content is large. This has implications for dark matter searches.
