Abstract

The parity violation parameters [Formula presented] and [Formula presented] of the [Formula presented] and [Formula presented] couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the [Formula presented] pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993–1998 SLD sample of 550 000 [Formula presented] decays produced with highly polarized electron beams, we measure [Formula presented], and [Formula presented].
