| Abstract | Predictions are made within the scope of perturbative quantum chromodynamics and the nonrelativistic two-quark baryon model of the magnitude and dependence upon z (the fraction of the momentum of the heavy quark carried off by the baryon) of the longitudinal spin asymmetry parameter A/sub RL/ in the direct creation of Lambda /sub b / and Lambda /sub c/ baryons in the Z/sup 0/-boson channel in the LEP e/sup +/e/sup -/ collider. An estimate is found for the value of A /sub RL/( Lambda /sub b/) in the cascade production of Lambda /sub b/ baryons. (27 refs). |
