Bluon bremsstrahlung in e+e- annihilation. Pt. 2

The linear and circular polarizations of gluons emitted in electron-positron annihilation, e+e- → qanti qg, are evaluated, including neutral current and beam polarization effects. For the lower part of the gluon bremsstrahlung spectrum, the linear polarization is found to be large and the plane of polarization to be almost parallel to the qanti qg event plane. The neutral current induced circular polarization is in the upper part of the gluon spectrum of the order of 10-15% at 40 GeV total energy and reaches approx. equal to 50% at asymptotic energies.
