Parity Violation in Polarized Electron Scattering
Parity violation has been well established in particle physics for many years, since the 1950's where it was. first seen in beta decay processes. The strong and electromagnetic forces are parity conserving, and the experimental evidence that parity was not conserved in weak processes came somewhat as a surprise. The weak forces are responsible for the decay of radioactive nuclei, and it was in ...
متن کاملParity violation in quasifree electron scattering off the deuteron
For deuteron electroweak disintegration, parity violating effects are investigated which arise from the interference of γ and Z exchange as well as from the hadronic sector via a small parity violating component in the deuteron. The general formalism for the differential cross section and polarization observables of electromagnetic deuteron disintegration is extended to incorporate parity viola...
متن کاملFurther Tests of Parity Violation in Inelastic Electron Scattering
Further measurements of parity violating asymmetries in inelastic scattering of polarized electrons from deuterium have been made for a range of y values from 0.15 to 0.36. Only a small y-dependence is observed in the asymmetries. Using the quark-parton model our results are in good agreement with the Weinberg-Salam predictions. 0.020. We obtain a value of the parameter sin2f3W= 0.224 ?r The ev...

متن کاملParity Violation in Proton-Proton Scattering
Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-proton parity violation experiments are presently either being performed or are being prepared for execution in the near future: at TRIUMF at ...
