The strangeness content of the nucleon

High Energy Physics - Lattice 2008-11-26 v1

Abstract

We evaluate the matrix element of qˉq\bar{q} q 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 sˉs\bar{s} s content is large. This has implications for dark matter searches.
