Circularly polarized gluons emitted in high energy QCD processes

In the light of the recent report by the ALEPH Collaboration [D. Buskulic et al., Phys. Lett. B 365, 437 (1996)] where {\ensuremath{\Lambda}}_{b}polarization was measured, which involves polarization transfer from the b quark to {\ensuremath{\Lambda}}_{b},we discuss the gluon circular polarization created in high energy {e}^{+}{e}^{\ensuremath{-}}annihilation, previously calculated, and give a calculation of gluon circular polarization...
