Selected Parity Violation Experiments

Nuclear Experiment 2007-05-23 v1

Abstract

I start by reviewing existing pp\vec{p}p measurements with particular emphasis on the recent 221 MeV pp\vec{p}p measurement at TRIUMF which permitted the weak meson-nucleon coupling constants hρpph^{pp}_\rho and hωpph^{pp}_\omega to be determined separately for the first time. I then review np\vec{n}p experiments, with specific details of the npdγ\vec{n}p \to d\gamma experiment now under preparation at Los Alamos National Laboratory. This experiment will provide a clean measurement of the weak pion nucleon coupling, fπf_\pi. Finally, I discuss ep\vec{e}p parity violation experiments, particularly the Gzero experiment under way at Jefferson Lab in Virginia. This experiment will measure the weak form factors GEzG_E^z and GMzG_M^z, allowing the distribution of strange quarks in the quark sea to be determined.
