Abstract
We investigate the prospects of measuring the strange quark distribution function at the Tevatron, using W plus charm quark events. The W plus charm quark signal produced by strange quark--gluon fusion, sg→ W-c and sg→ W+ c, is approximately 5\% of the inclusive W+1 jet cross section for jets with a transverse momentum pT(j)>10~GeV. We study the sensitivity of the W plus charm quark cross section to the parametrization of the strange quark distribution function, and evaluate the various background processes. Strategies to identify charm quarks in CDF and D0/ are briefly described.
