Parity-Violating Interaction Effects I: the Longitudinal Asymmetry in pp Elastic Scattering
نویسنده
چکیده
The proton-proton parity-violating longitudinal asymmetry is calculated in the lab-energy range 0–350 MeV, using a number of different, latest-generation strong-interaction potentials–Argonne v18, Bonn-2000, and Nijmegen-I–in combination with a weak-interaction potential consisting of ρand ω-meson exchanges–the model known as DDH. The complete scattering problem in the presence of parity-conserving, including Coulomb, and parity-violating potentials is solved in both configurationand momentum-space. The predicted parity-violating asymmetries are found to be only weakly dependent upon the input strong-interaction potential adopted in the calculation. Values for the ρand ω-meson weak coupling constants hpp ρ and h pp ω are determined by reproducing the measured asymmetries at 13.6 MeV, 45 MeV, and 221 MeV. 21.30.+y, 24.80.-x, 25.40.Cm Typeset using REVTEX 1

Parity-Violating Interaction Effects in the np System
We investigate parity-violating observables in the np system, including the longitudinal asymmetry and neutron-spin rotation in ~np elastic scattering, the photon asymmetry in ~np radiative capture, and the asymmetries in deuteron photo-disintegration d(~γ, n)p in the threshold region and electrodisintegration d(~e, e)np in quasi-elastic kinematics. To have an estimate of the model dependence f...
متن کاملVacuum polarization radiative correction to the parity violating electron scattering on heavy nuclei
Experimental investigations of the proton ρp(r) and neutron ρn(r) densities in heavy nuclei are very important for testing of various nuclear models. The densities are also important for many applications like, for example, precise calculations of atomic parity nonconservation. While the charge distribution (proton density) is known pretty well mainly due to data on the elastic electron scatter...

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...
