The next generation HAPPEX experiments
A new generation of parity violating electron scattering experiments began running in Summer 2004 at the Thomas Jefferson National Accelerator Facility. HAPPEX-H will measure the parity violating asymmetry in polarized electron scattering from protons at Q2 = 0.11 (GeV/c)2. This asymmetry is sensitive to a linear combination of the strange electric and magnetic form factors of the proton. HAPPEX-He will measure the parity violating asymmetry in polarized electron scattering from a 4He target at the same value of Q2, using the same spectrometers and similar detectors, accessing the strange electric form factor cleanly. PREX will use parity violating electron scattering to determine the neutron radius of the 206Pb nucleus.
