| Abstract: | In order to reach completely the vector and axial couplings of the neutral currents to quarks we propose to measure quark helicities from the polarizations of the leading baryons of the jets. Applications are given for e+e? → 2 jets where large degrees of polarization are obtained from γ-Z interference. |
