OSTI ID:6059765
Parity nonconservation was observed in the inelastic scattering of longitudinally polarized electrons from an unpolarized deuterium target at 19.4 and 22.2 GeV. An asymmetry A = (sigma/sub R/ - sigma/sub L)/(sigma/sub R/ + sigma/sub L/) = (-9.5 +- 1.6) x 10/sup -5/ Q/sup 2/, Q/sup 2/ in (GeV/c)/sup 2/ was found for values of Q/sup 2/ near 1.4. The statistical and systematic errors are each about 9 percent of the measured asymmetry. This result is consistent with predictions from the standard Weinberg--Salam SU(2) x U(1) model. Using the simple quark-parton model of the nucleon, the value sin /sup 2/theta/sub W/ = 0.20 +- 0.03 is obtained. 21 references.
