Parity 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 ...
متن کاملParity violation in elastic electron-proton scattering and the Proton's strange magnetic form factor
We report a new measurement of the parity-violating asymmetry in elastic electron scattering from the proton at backward scattering angles. This asymmetry is sensitive to the strange magnetic form factor of the proton as well as electroweak axial radiative corrections. The new measurement of A = -4.92+/-0.61+/-0.73 ppm provides a significant constraint on these quantities. The implications for ...
متن کاملNew Measurement of Parity Violation in Elastic Electron-Proton Scattering and Implications for Strange Form Factors
We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from the proton. The result is A = −15.05±0.98(stat)± 0.56(syst) ppm at the kinematic point 〈θlab〉 = 12.3 and 〈Q2〉 = 0.477 (GeV/c). The value for the strange form factor (GE +0.392G s M )/(G p M/μp) = 0.069± 0.056± 0.039 is extracted from the data, where the first error is experimental a...
متن کاملElectromagnetic radiative corrections in parity-violating electron-proton scattering
QED radiative corrections have been calculated for leptonic and hadronic variables in parityviolating elastic ep scattering. For the first time, the calculation of the asymmetry in the elastic radiative tail is performed without the peaking-approximation assumption in hadronic variables configuration. A comparison with the PV-A4 data validates our approach. This method has been also used to eva...
متن کاملGluon Contributions to Parity-Violating Asymmetries in Polarized Proton-Proton Scattering
We report on a calculation of one-loop weak corrections to polarized quark-gluon scattering and the corresponding crossed channels. Such contributions are suppressed formally by one power of αs relative to W− or Z−mediated quark-quark scattering, but would enable the spin asymmetry of the gluon distribution to contribute to parity-violating asymmetries that will soon be investigated in polarize...
