Parity-violating electron-deuteron scattering

The longitudinal asymmetry due to Z(0) exchange is calculated in quasielastic electron-deuteron scattering at momentum transfers \Q(2)\ similar or equal to 0.1GeV(2) relevant for the SAMPLE experiment. The deuteron and pn-scattering-state wave functions are obtained from solutions of a Schrodinger equation with the Argonne v(18) potential. Electromagnetic and weak neutral one- and two-nucleon currents are included in the calculation. The two-nucleon currents of pion range are shown to be identical to those derived in chiral perturbation theory. The results indicate that two-body contributions to the asymmetry are small (similar or equal to 0.2%) around the quasielastic peak, but become relatively more significant (similar or equal to 3%) in the high-energy wing of the quasielastic peak.
