Abstract: A forward-backward asymmetry A, consistent with that expected from the [gamma]-Z0 interference term in the process , is observed in the laboratory production angular distribution of high-momentum [logical and] baryons. The data were collected with the High Resolution Spectrometer at PEP. The asymmetry for [logical and] baryons with fractional energy greater than 0.3 is A = (-23+/- 8plusmn; 2)%.
