Abstract

The parity-violating asymmetry was investigated in quasielastic electron scattering from deuteron with determination of neutral weak axial vector form factor. The backward angles at Q2 = 0.038 (GeV/c)2 from deuteron scattering provided value of neutral weak axial vector form factor of nucleon with potentially large electroweak corrections. The scattered electron events were generated uniformly in energy, angle and position along target length in simulation. The correction factor for radiative effects was evaluated by comparing asymmetry with radiative effects included in simulation.
