Search for Jet Handedness in Hadronic Z0 Decays

We have searched for signatures of polarization in hadronic jets from Z0→qq¯ decays using the “jet handedness” method. The polar angle asymmetry induced by the high SLAC Linear Collider electron-beam polarization was used to separate quark jets from antiquark jets, expected to be left and right polarized, respectively. We find no evidence for jet handedness in our global sample or in a sample of light quark jets, and we set upper limits at the 95% C.L. of 0.063 and 0.099, respectively, on the magnitude of the analyzing power of the method proposed by Efremov et al.
