Selected Parity Violation Experiments
نویسنده
چکیده
I start by reviewing existing ~ pp measurements with particular emphasis on the recent 221 MeV ~pp measurement at TRIUMF which permitted the weak meson-nucleon coupling constants h ρ and h pp ω to be determined separately for the first time. I then review ~np experiments, with specific details of the ~np → dγ experiment now under preparation at Los Alamos National Laboratory. This experiment will provide a clean measurement of the weak pion nucleon coupling, fπ. Finally, I discuss ~ep parity violation experiments, particularly the Gzero experiment under way at Jefferson Lab in Virginia. This experiment will measure the weak form factors GzE andG z M , allowing the distribution of strange quarks in the quark sea to be determined.

Reevaluation of the role of nuclear uncertainties in experiments on atomic parity violation with isotopic chains
In light of new data on neutron distributions from experiments with antiprotonic atoms @Trzcinska et al., Phys. Rev. Lett. 87, 082501 ~2001!#, we reexamine the role of nuclear-structure uncertainties in the interpretation of measurements of parity violation in atoms using chains of isotopes of the same element. With these new nuclear data, we find an improvement in the sensitivity of isotopic c...
متن کاملParity violation in hydrogen revisited
We reconsider parity violation experiments in atomic hydrogen and deuterium in the light of existing tests of the Electroweak interactions, and assess whether new experiments, using improved experimental techniques, could make useful contributions to testing the Standard Model (SM). We find that, if parity experiments in hydrogen can be done, they remain highly desirable because there is neglig...
متن کاملParity Violation in Pp and Np Experiments
Parity violation experiments involving only two nucleons provide a way to study the non-leptonic, strangeness-conserving part of the weak interaction in a clean measurement free of nuclear structure uncertainties. Such measurements are particularly appropriate for discussion at this conference as their success depends critically on the ability to accurately control and measure spin. Although si...
متن کاملImproving the Hadron Physics of Non-Standard-Model Decays: Example Bounds on R-parity Violation
Using the example of selected decays driven by R-parity-violating supersymmetric operators, we demonstrate how strong final-state interactions can be controlled quantitatively with high precision, thus allowing for a more accurate extraction of effective parameters from data. In our examples we focus on the lepton-flavor-violating decays τ → μπ+π−. In R-parity violation these can arise due to t...
متن کاملParity Violation in Astrophysics
Core collapse supernovae are gigantic explosions of massive stars that radiate 99% of their energy in neutrinos. This provides a unique opportunity for large scale parity or charge conjugation violation. Parity violation in a strong magnetic field could lead to an asymmetry in the neutrino radiation and recoil of the newly formed neutron star. Charge conjugation violation in the neutrino-nucleo...
