TODO - Transversely polarized baryon-antibaryon (in particular Lambda-($) over
bar Lambda) back-to-back production in e(-)e(+) collisions is studied.
Higher order (one-loop) corrections (HOC) are determined and K-factors
well exceeding unity are found. For the two cases that the spin vectors
of Lambda and ($) over bar Lambda are: (a) on the production plane and
(b) perpendicular to it, the differential inclusive cross sections are
found to have opposite sign; this feature is characteristic of the
process both at the Born and one-loop level, and is independent of the
magnitude and shape of the fragmentation functions or other aspects of
the calculation. The dominance of HOC by soft, collinear and virtual
gluons is also considered.
