Abstract

We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from C12 nuclei. Our result is Aexpt=0.60±0.14±0.02 ppm, where the first error is statistical and the second is systematic. With a beam polarization of 0.37, we compute the isoscalar vector hadronic coupling constant I to be 0.136±0.032±0. 009. The standard model predicts I=0.155 at the tree level, in agreement with our data.
