Overview of Issues Surrounding Strangeness in the Nucleon

Abstract

The calculation of the strangeness content of the nucleon and its experimental verification is a fundamental step in establishing non-perturbative QCD as the correct theory describing the structure of hadrons. It holds a role in QCD analogous to the correct calculation of the Lamb shift in QED. We review the latest developments in the vector and scalar matrix elements of the strange quarks in the proton, where there has recently been considerable progress.Comment: Invited presentation at the 10th Conference on the Intersection of Nuclear and Particle Physics, San Diego, May 26-May 30, 200
