Strange quark contribution and polarization observables in elastic electron deuteron scattering

Parity-violating asymmetries in polarized electron scattering from nucleons and nuclei result from the interference of photon (γ) and Z-exchange. These processes are therefore considered to be ideal for studying the structure of hadrons and in particular to understand the role of sea quarks in the structure of nucleons. In the case of the elastic scattering of polarized electrons from unpolarized deuterons, we have calculated the parity violating helicity-dependent electron asymmetry as well as the parity-violating non vanishing components of the recoil deuteron polarization. In this paper we have studied the parity-violating observables, in elastic scattering of polarized and unpolarized electrons from unpolarized deuteron targets at electron energies relevant for SAMPLE, PVA4 and G0 experiments
