Longitudinal Contribution to the Alignment Polarization of Quarks Produced in e+ e- Annihilation: An O(alpha_s) Effect

S. Groote, J. G. K"orner, M. M. Tung

We calculate the longitudinal contribution to the alignment polarization $\Pl$ of quarks produced in $e^{+}{e}^{-}$ annihilation. In the Standard Model, the longitudinal alignment polari…
