Ap. Contogouris et al., TRANSVERSELY POLARIZED BARYON-ANTIBARYON PRODUCTION IN E(-)E(+) COLLISIONS, Physics letters. Section B, 344(1-4), 1995, pp. 370-376
Transversely polarized baryon-antibaryon (in particular Lambda-($) ove
r bar Lambda) back-to-back production in e(-)e(+) collisions is studie
d. Higher order (one-loop) corrections (HOC) are determined and K-fact
ors well exceeding unity are found. For the two cases that the spin ve
ctors of Lambda and ($) over bar Lambda are: (a) on the production pla
ne and (b) perpendicular to it, the differential inclusive cross secti
ons are found to have opposite sign; this feature is characteristic of
the process both at the Born and one-loop level, and is independent o
f the magnitude and shape of the fragmentation functions or other aspe
cts of the calculation. The dominance of HOC by soft, collinear and vi
rtual gluons is also considered.
