The next generation HAPPEX experiments

  • Richard S. Holmes
Conference paper

Abstract

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 Q 2 = 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 Q 2, 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.
