The HAPPEX experiment at Jefferson Laboratory
Conference

OSTI ID:833154
A new experimental program is under way at Jefferson Laboratory to probe the strange structure of the nucleon via parity violating electron scattering, HAPPEX is the first experiment from this program to run Jefferson Laboratory. We describe the physics motivation, provide an experimental overview and report on the results from the first data run. The asymmetry for the elastic scattering of 3.3 GeV electrons off target protons at a scattering angle of 12.5 degrees was measured to a precision of 15% of itself. The contribution from strange quark form factors was found to be zero within the experimental and theoretical uncertainties.
