Wave Functions for Parity–Violating Nuclear Forces
Tensor representation (TR) for wave function (WF) of three–nucleon bound state with the total angular momentum I = 1/2 is discussed. The WF in TR has 16 complex components depending on vectors of relative momenta. Constraints on the WF imposed by requirements of invariance with respect to space inversion and time reversal are studied. Both parity– even and parity–odd components of the 3N bound ...
متن کاملParity Violating Measurements of Neutron Densities and Nuclear Structure
Parity violating electron nucleus scattering is a clean and powerful tool for measuring the spatial distributions of neutrons in nuclei with unprecedented accuracy. Parity violation arises from the interference of electromagnetic and weak neutral amplitudes, and the Z of the Standard Model couples primarily to neutrons at low Q. Experiments are now feasible at existing facilities. We show that ...
متن کامل0 Parity and time reversal violating nuclear polarizability
We propose a nuclear mechanism which can induce an atomic electric dipole moment (EDM). Parity and time reversal violating (P, T-odd) nuclear forces generate a mixed P, T-odd nuclear polarizability β ik (defined by an energy shift U = −β ik E i H k , E is electric field and H magnetic field). The interaction of atomic electrons with β ik produces an atomic EDM. We performed an analytical calcul...
متن کاملParity-Violating Electron Scattering
Measurements of parity-violating asymmetries in the scattering of longitudinally polarized electrons off unpolarized fixed targets are used to access leptonic and semi-leptonic weak neutral current amplitudes. One thrust of the current program is the measurement the elastic neutral weak amplitude at very low Q from scattering off a heavy spinless nucleus, which is sensitive to the presence of a...
متن کاملParity-violating Longitudinal Response
The parity-violating quasielastic electron scattering response is explored within the context of a model that builds antisymmetrized random phase approximation and Hartree-Fock correlations on a relativistic Fermi gas basis. Particular emphasis is put on the weak-neutral longitudinal response function, since this observable displays a strong sensitivity to isospin correlations: specifically, it...
